When the job is completed, the AppMaster will exit. At > this time, if the job client have not got the job completed event from > AppMaster, it will switch to get job report from history server. > But in HBaseTestingUtility#startMiniMapReduceCluster, the config: > mapreduce.jobhistory.address is not copied to TestUtil's config. > > CRUNCH-249 reported the same problem. -- This message was sent by Atlassian JIRA (v6.2#6252)
