[jira] [Commented] (HADOOP-7884) test-patch seems to fail when a patch goes across projects (common/hdfs/mapreduce) or touches hadoop-assemblies/hadoop-dist.

Tom White commented on HADOOP-7884:
-----------------------------------

The test-patch builds run with the base directory set to hadoop-{common,hdfs,mapreduce}-project. We could change common so it is run from the top-level, thus allowing cross-project patches, but it would mean that i) unit tests for every project are run for every change, and ii) only patches relative to the top-level would apply. i) is probably a good thing (changes to common should result in HDFS and MapReduce tests being run). For ii), do folks generally produce patches from the top-level anyway?

> Take for example HDFS-2178, the patch applies cleanly, but test-patch fails.
