Chris Nauroth updated HADOOP-11984:
-----------------------------------
Attachment: HADOOP-11984.024.patch
I agree that we're really close, and the ~4x reduction in time for
hadoop-common tests highlighted by Steve sure is pleasant. :-)
I'm attaching patch v024 with 2 changes:
# pom.xml no longer defines {{test.build.shared.data}}. Vinay solved this
problem differently by using {{ServerSocketUtil#getPort}}, so there is no
longer a need for a shared directory for multiple JUnit processes to coordinate
with lock files corresponding to ports.
# Since the HDFS fixes have been spun off into the separate HDFS-9139 JIRA, we
need to be careful not to trigger {{-Pparallel-tests}} for HDFS builds until
after that gets completed. To help move things forward for hadoop-common, I've
introduced a temporary hack in test-patch.sh so that it only uses
{{-Pparallel-tests}} for the hadoop-common build.
> Enable parallel JUnit tests in pre-commit.

> for running JUnit tests in multiple concurrent processes. This issue
> proposes to activate that profile during pre-commit to speed up execution.
