Key Bug Fixes

TicketDescription
TD-56170The Test Connection button for some relational connection types does not perform a test authentication of user credentials.
TD-54440

Header sizes at intermediate nodes for JDBC queries cannot be larger than 16K.

Previously, the column names for JDBC data sources were passed as part of a header in a GET request. For very wide datasets, these GET requests often exceeded 16K in size, which represented a security risk.

The solution is to turn these GET requests into ingestion jobs.

Info

NOTE: To mitigate this issue, JDBC ingestion and JDBC long loading must be enabled in your environment. For more information, see Configure JDBC Ingestion.



New Known Issues

TicketDescription
TD-58818

Cannot run jobs on some builds HDP 2.6.5 and later. There is a known incompatibility between HDP 2.6.5.307-2 and later and the Hadoop bundle JARs that are shipped with the

D s item
iteminstaller
.

Tip

Solution: The solution is to use an earlier compatible version. For more information, see Configure for Hortonworks.


TD-58523

Cannot import dataset with filename in Korean alphabet from HDFS.

Tip

Workaround: You can upload files with Korean characters from your desktop. You can also add a 1 to the end of the file on HDFS, and it can then be imported.


TD-55299

Imported datasets with encodings other than UTF-8 and line delimiters other than \n may generate empty outputs on Spark or

D s dataflow
running environments.

TD-51516

Input data containing BOM (byte order mark) characters may cause Spark or

D s dataflow
running environments to read data improperly and/or generate invalid results.

Release 8.0

January 26, 2021

What's New

APIs:

  • Individual workspace users can be permitted to create and use their own access tokens for use with the REST APIs. For more information, see Workspace Settings Page.

  • Improved method for conversion and ingestion of XLS/XSLX files. For more information, see Import Excel Data.

...

  • You can enable the
    D s webapp
    to apply SQL filter pushdowns to your relational datasources to remove unused rows before their data is imported for a job execution. This optimization can significantly improve performance as less data is transferred during the job run. For more information, see Flow Optimization Settings Dialog.
  • Optimizations that were applied during the job run now appear in the Job Details Page. See Job Details Page.


Changes in System Behavior

None.

Key Bug Fixes

TicketDescription
TD-57354

Cannot import data from Azure Databricks. This issue is caused by an incompatibility between TLS v1.3 and Java 8, to which it was backported.

TD-57180

AWS jobs run on Photon to publish to HYPER format fail during file conversion or writing.

New Known Issues

TicketDescription
TD-56170

The Test Connection button for some relational connection types does not perform a test authentication of user credentials.

Tip

Workaround: Append the following to your Connect String Options:

Code Block
;ConnectOnOpen=true

This option forces the connection to validate user credentials as part of the connection. There may be a performance penalty when this option is used.
