Changes to System Behavior

Hadoop Pig running environment is no longer available

As of Release 4.1, the Pig running environment is no longer available for execution of jobs. Implications:

• Deployments that are connected to a Hadoop cluster must use Spark for job execution. See Configure Spark Running Environment.
• CLI scripts that reference running jobs on the pig running environment must be updated.
• Integration with Cloudera Navigator is not supported in this release.
• Integration with HDI/WASB is supported but may require further configuration. Please contact Alteryx Support.

Python UDFs are no longer available

With the removal of the Hadoop Pig running environment, Python user-defined functions are no longer available. 

Transform Editor has been removed

In Release 4.0.1 and earlier, you could type in  Wrangle transformation steps as plain text in the Transform Editor as well as use the Transform Builder. 

In Release 4.1 and later, the Transform Editor has been removed, in favor of an enhanced version of the Transform Builder.

See Transform Builder.

Dependencies Browser has been replaced

In Release 4.0.1, you could explore dependencies between your datasets through the Dependencies Browser, which was accessible through a graph in the toolbar in the Transformer page. 

In Release 4.1, this browser has been replaced by the Dataset Navigator. In the Transformer page, click the drop-down next to the name of the current dataset. In the Dataset Navigator, you can browse the datasets through a list or flow view to locate another wrangled dataset to load.

In Release 4.2 and later, this browser has been renamed to the Recipe Navigator. See Recipe Navigator. 

Manual database installation is no longer required

Prior to Release 4.0, the databases had to be installed manually. 

In Release 4.0 and later, the databases are installed for you on the local server as part of the basic install process. For more information, see Install Databases.

If you need to re-install the databases, manual steps are still available. See Install Databases for PostgreSQL.

Head sample replaced by random sample on upgrade

In Release 4.0 and earlier, if your dataset used the initial rows (head) sample in the data grid, this sample is replaced by the random sample after the upgrade.

Miscellaneous

• The Send a Copy feature introduced in Release 4.0 has been integrated with the general sharing capabilities. See Share Flow Dialog.
• Ah-hoc publishing to Redshift in CSV format is no longer supported. See Publishing Dialog.
