job.xml should add crc check in tasktracker and sub jvm.
--------------------------------------------------------
Key: MAPREDUCE-1254
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1254
Project: Hadoop Map/Reduce
Issue Type: New Feature
Components: task, tasktracker
Affects Versions: 0.22.0
Reporter: ZhuGuanyin
Currently job.xml in tasktracker and subjvm are write to local disk through
ChecksumFilesystem, and already had crc checksum information, but load the
job.xml file without crc check. It would cause the mapred job finished
successful but with wrong data because of disk error. Example: The tasktracker
and sub task jvm would load the default configuration if it doesn't
successfully load the job.xml which maybe replace the mapper with
IdentityMapper.
