------------------------------------

             Summary: ATS 1.5 parse pipeline to consider handling open() events recoverably
                 Key: YARN-4705
                 URL: https://issues.apache.org/jira/browse/YARN-4705
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor


During one of my own timeline test runs, I've been seeing a stack trace warning that the CRC
check failed in Filesystem.open() file; something the FS was ignoring.

Even though its swallowed (and probably not the cause of my test failure), looking at the
code in {{LogInfo.parsePath()}} that it considers a failure to open a file as unrecoverable.


on some filesystems, this may not be the case, i.e. if its open for writing it may not be
available for reading; checksums maybe a similar issue. 

Perhaps a failure at open() should be viewed as recoverable while the app is still running?
