Description
TestJobHistory fails.
>>> org.apache.hadoop.mapred.TestJobHistory.testDoneFolderOnHDFS
>>> org.apache.hadoop.mapred.TestJobHistory.testDoneFolderNotOnDefaultFileSystem
>>> org.apache.hadoop.mapred.TestJobHistory.testHistoryFolderOnHDFS
>>> org.apache.hadoop.mapred.TestJobHistory.testJobHistoryFile
It looks like this was introduced by MAPREDUCE-3349 and the issue is that the test expects the hostname to be in the format rackname/hostname, but with 3349 it split those apart into 2 different fields.
