Issue

The issue with Yarn client if Job server was not used and a particular group of jars were sent when they should not be has been resolved.

Unable to build BD Streaming Job

Building Spark Streaming Jobs when migrating from version 6.5 to version 7.3 using MapR 6.0.1 as a custom distribution now works successfully.

Compilation error with migrated Job

The compilation error "String literal is not properly closed by a double-quote" that appears when migrating from version 6.4 to version 7.3 has ben solved with an intermediate migration to a lower 7.x version.

tFileOutputDelimited applies trim operation but should not

Spark UI problem (org.glassfish.jersey.servlet.ServletContainer.service)

Issue

Description

Performance issue at Talend Studio startup Talend Studio startup performance has been improved through:
  • performing validation checks only on the patches that have not been installed

  • removing the unnecessary check of each plugin when validating the license
