Subject [jira] [Commented] (HADOOP-12111) [Umbrella] Split test-patch off into its own TLP
Date Wed, 01 Jul 2015 19:38:05 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12111?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14610892#comment-14610892

Allen Wittenauer commented on HADOOP-12111:

A super-complex test case:  https://issues.apache.org/jira/browse/HADOOP-11984?focusedCommentId=14566293&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14566293

I don't know if I can list all the things that the patch actually tests because it hits so
many subsystems.  Highlights are that it used multijdk, uses parallel test execution,  and
extra native compile time flags that are specific to Hadoop.

Two interesting bugs highlighted:
* checkstyle output can be multi-line, which makes it tricky to handle when doing before/after
comparisons like we want to do.  (cc: [~romani]) 
* findbugs convertXmlToText is only failing for one of the modules and we do a pretty bad
job of giving any hints as to why.   Filed HADOOP-12166 to see if we can do better.
* I'm assuming the mvn install convergence errors are just typical maven stupidity w/multiple
writers. [HADOOP-12146 should alleviate a lot of that.]
* Hadoop-specific: we might need to bump up the unit test heap for JDK8. :(

> Given test-patch's tendency to get forked into a variety of different projects, it makes
a lot of sense to make an Apache TLP so that everyone can benefit from a common code base.
