Description

Failed tests: test0[0](org.apache.hadoop.fs.TestLocalDirAllocator): Checking for build/test/temp/RELATIVE1 in build/test/temp/RELATIVE0/block2860496281880890121.tmp - FAILED!
test0[1](org.apache.hadoop.fs.TestLocalDirAllocator): Checking for /data/md0/hadoop-common/hadoop-common-project/hadoop-common/build/test/temp/ABSOLUTE1 in /data/md0/hadoop-common/hadoop-common-project/hadoop-common/build/test/temp/ABSOLUTE0/block7540717865042594902.tmp - FAILED!
test0[2](org.apache.hadoop.fs.TestLocalDirAllocator): Checking for file:/data/md0/hadoop-common/hadoop-common-project/hadoop-common/build/test/temp/QUALIFIED1 in /data/md0/hadoop-common/hadoop-common-project/hadoop-common/build/test/temp/QUALIFIED0/block591739547204821805.tmp - FAILED!

The recently added testRemoveContext() (MAPREDUCE-4379) does not clean up after itself, so if it runs before test0 (due to undefined test ordering on JDK7), test0 fails. This can be fixed by wrapping it with

try { ... } finally { rmBufferDirs(); }
