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. > > -- > This message is automatically generated by JIRA. > - > You can reply to this email to add a comment to the issue online. > >
