Subject [jira] [Commented] (HDFS-8381) Reduce time taken for complete HDFS unit test run
Date Tue, 12 May 2015 23:52:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-8381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14541044#comment-14541044
] 

Allen Wittenauer commented on HDFS-8381:
----------------------------------------

We've talked about enabling parallel tests (mvn -Pparallel-tests) in various test-patch.sh
jiras and discussions.  Some work was done on making sure that worked a year or two ago (HADOOP-9287),
so it might not be that bad to make sure it still works. If it does, we can add that to the
mvn command line and see how that helps the time.

> HDFS unit tests take a long time to run. Our unit tests are more like system/integration
tests since we spin up a MiniDFSCluster for individual test cases. A number of tests have
sleeps which further adds to the run time.
> A better option is to use more fine-grained unit tests specific to individual classes.
I did not find any existing Jiras for this so filing one to track this work.
