By default, under SSO manual logout and session expiration logout redirect to different pages. Manual logout directs you to SAML sign out, and session expiry produces a session expired page.

To redirect the user to a different URL on session expiry, an administrator can set the following parameter: webapp.session.redirectUriOnExpiry. This parameter applies to the following SSO environments:

Connection files used by the data service are not persisted in a Dockerized environment.

Tip

Workaround: In the Admin Settings page, set data-service.vendor to a location that is persisted. Example value:

Code Block

...

Platform appears to fail to restart properly through Admin Settings page due to longer restarts of individual services. Symptoms:

  • Changes to settings may appear to have not been applied.
  • Admin Settings page appears to be stuck restarting.
Tip

Workaround: Restart can take up to several minutes. If the restart does not appear to complete, try reloading the page. If that doesn't work, restarting from the command line is more reliable. See Start and Stop the Platform.

Release 6.8

December 6, 2019

Welcome to Release 6.8 of 

D s product
rtrue
. This release introduces several key features around operationalizing the platform across the enterprise. Enterprise stakeholders can now receive email notifications when recurring jobs have succeeded or failed, updating data consumers outside of the platform. This release also introduces a generalized webhook interface, which facilitates push notifications to applications such as Slack when jobs have completed. When jobs fail, users can download a much richer support bundle containing configuration files, script files, and a specified set of log files. 

...

In the application, you can now use shortcut keys to navigate around the workspace and the Transformer page. And support for the Firefox browser has arrived. Read on for more goodness added with this release.

What's New

Install:

Workspace:


  • Individual users can now enable or disable keyboard shortcuts in the workspace or Transformer page. See User Profile Page.
  • Configure locale settings at the workspace or user level. See Locale Settings.
  • You can optionally duplicate the datasets from a source flow when you create a copy of it. See Flow View Page.
  • Create a copy of your imported dataset. See Library Page.

...

...

  • Download logs bundle on job success or failure now contains extensive configuration information to assist in debugging. For more information, see see Configure Support Bundling.

...

  • Support for integration with EMR 5.8 - 5.27. For more information, see Configure for EMR. 


...

  • Support for using non-default database for your Snowflake stage.

...

  • Select columns, functions applied to your source, and constants to replace your current dataset. See Select.

  • Improved Date/Time format selection. See Choose Datetime Format Dialog.

    Tip

    Tip: Datetime formats in card suggestions now factor in the user's locale settings for greater relevance.


  • Improved matching logic and performance when matching columns through RapidTarget. 
    • Align column based on the data contained in them, in addition to column name. 
    • This feature is enabled by default. For more information, see Overview of RapidTarget.
  • Improvements to the Search panel enable faster discovery of transformations, functions, and other objects. See Search Panel.

Job execution:

  • By default, the 
    D s webapp
     permits up to four jobs from the same flow to be executed at the same time. If needed, you can configure the application to execute jobs from the same flow one at a time. See Configure Application Limits.

  • If you enabled visual profiling for your job, you can download a JSON version of the visual profile. See Job Details Page.




Language:

API:

  • Apply overrides at time of job execution via API. 
  • Define import mapping rules for your deployments that use relational sources or publish to relational targets. 
  • Export and import macro definitions.
  • See Changes to the APIs.

Changes in System Behavior

Browser Support Policy:

  • For supported browsers, at the time of release, the latest stable version and the two previous stable versions are supported.

    Info

    NOTE: Stable browser versions released after a given release of

    D s product
    will NOT be supported for any prior version of
    D s product
    .  A best effort will be made to support newer versions released during the support lifecycle of the release.

    For more information, see Desktop Requirements.

Install:

Info

NOTE: In the next release of

D s product
after Release 6.8, support for installation on CentOS/RHEL 6.x and Ubuntu 14.04 will be deprecated. You should upgrade the
D s node
to a supported version of CentOS/RHEL 7.x or Ubuntu 16.04. Before performing the upgrade, please perform a full backup of the
D s platform
and its databases. See Backup and Recovery.



  • Support for Spark 2.1 has been deprecated. Please upgrade to a supported version of Spark.
    • Support for EMR 5.6 and eMR 5.7 has also been deprecated. Please upgrade to a supported version of EMR. 
    • For more information, see Product Support Matrix.
  • To simplify the installation distribution, the Hadoop dependencies for the recommended version only are included in the software download. For the dependencies for other supported Hadoop distributions, you must download them from the 
    D s item
    itemFTP site
     and install them on the 
    D s node
    . See Install Hadoop Dependencies.  
  • D s node
     has been upgraded to use Python 3. This instance of Python has no dependencies on any Python version external to the 
    D s node
    .

...

Info

NOTE: Do not attempt to connect to the

D s platform
using any version of the CLI or the v3 endpoints. They are no longer supported and unlikely to work.

In Release 6.4:

  • The Command Line Interface The Command Line Interface (CLI) was deprecated. Customers must use the v4 API endpoints instead.
  • The v3 versions of the API endpoints were deprecated. Customers must use the v4 API endpoints instead.

Key Bug Fixes

TicketDescription
TD-40348

When loading a recipe in an imported flow that references an imported Excel dataset, Transformer page displays Input validation failed: (Cannot read property 'filter' of undefined) error, and the screen is blank.

TD-42080Cannot run flow or deployment that contains more than 10 recipe jobs


New Known Issues

Cannot modify the type of relational target for publishing action.

tipTD-45923
TicketDescriptionTD-46123

Workaround: Create a new publishing action with the desired relational target. Remove the original one if necessary. See Run Job Page.

Publishing a compressed Snappy file to SFTP fails.
TD-45922You cannot publish TDE format to SFTP destinations.
TD-45492

Publishing to Databricks Tables fails on ADLS Gen1 in user mode.

TD-45273

Artifact Storage Service fails to start on HDP 3.1.

Tip

Workaround: The Artifact Storage Service can reference the HDP 2.6 Hadoop bundle JAR.

Steps:

  1. D s config

  2. Locate the following property:

    Code Block
    "artifact-storage-service.classpath"


  3. Replace this value:

    Code Block
    :%(topOfTree)s/%(hadoopBundleJar)s


  4. With the following:

    Code Block
    :%(topOfTree)s/conf/hadoop-site/:%(topOfTree)s/hadoop-deps/hdp-2.6/build/libs/hdp-2.6-bundle.jar


  5. Save changes and restart the platform.


TD-45122

API: re-running job using only the wrangleDataset identifier fails even if the original job succeeds when writeSettings were specified.

Tip

Workaround: Use a full jobGroups job specification each time that you run a job.

See API JobGroups Create v4.

TD-44429

Cannot publish outputs to relational targets, receiving Encountered error while processing stream.

Tip

Workaround: This issue may be caused by the trifacta service account not having write and execute permissions to the /tmp directory on the

D s node
. If so, you can do either of the following:

  1. Enable write and execute permissions for the account on /tmp.

  2. Create a new temporary account and provide the service account write and execute permissions to it. Then, add the following to data-service.jvmOptions:

    Code Block
    -Dorg.xerial.snappy.tempdir=/new/directory/with/writeexecuteaccess



TD-44427

Cannot publish dataset containing duplicate rows to Teradata. Error message:

Code Block
Caused by: java.sql.SQLException: [Teradata Database] [TeraJDBC 15.10.00.14] [Error -2802] [SQLState 23000] Duplicate row error in abc_trifacta.tmp_218768523.
 at


Tip

Workaround: This is a known limitation on Teradata. For more information on this limitation, see Enable Teradata Connections.
