-----------------------------------------
Summary: Fix pre-commit builds to execute the right set of tests
Key: HADOOP-11779
URL: https://issues.apache.org/jira/browse/HADOOP-11779
Project: Hadoop Common
Issue Type: Bug
Components: scripts
Affects Versions: 2.7.0
Reporter: Karthik Kambatla
Priority: Critical
I have noticed that our pre-commit builds could end up running the "wrong" set
of unit tests for patches. For instance, YARN-3412 changes only YARN files, but
the test were run against one of the MR modules.
I suspect there is a race condition when there are multiple builds executing on
the same node, or remnants from a previous run are getting picked up.
