             Summary: TestLocalDirAllocator fails intermittently with JDK7
                 Key: HADOOP-8692
                 URL: https://issues.apache.org/jira/browse/HADOOP-8692
             Project: Hadoop Common
          Issue Type: Bug
         Environment: Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.7.0_04, vendor: Oracle Corporation
Java home: /usr/lib/jvm/jdk1.7.0_04/jre
Default locale: en_US, platform encoding: ISO-8859-1
OS name: "linux", version: "3.2.0-25-generic", arch: "amd64", family: "unix"

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