-------------------------------------------
Summary: JobHistoryServer has no information about applications if
the MR-AM crashes
Key: MAPREDUCE-5418
URL: https://issues.apache.org/jira/browse/MAPREDUCE-5418
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: jobhistoryserver, mr-am
Affects Versions: 2.0.5-alpha
Reporter: Karthik Kambatla
Priority: Critical
Currently, the AM writes the job-specific information to HDFS only after it
finishes; the JHS needs this info to display anything. If the AM fails, this
info is not written and the JHS fails to display anything for that job.
