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

             Summary: Ozone: Review logging where we are returning internal error in KSM and
SCM
                 Key: HDFS-12075
                 URL: https://issues.apache.org/jira/browse/HDFS-12075
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: ozone
    Affects Versions: HDFS-7240
            Reporter: Anu Engineer
            Priority: Minor
             Fix For: HDFS-7240


There are a bunch of places in SCM and KSM where we are returning "FAILED_INTERNAL_ERROR".
This often indicates some other component failure like DB or disk I/O. We should make sure
that we have detailed logs on server side which explains why the failure happened. We should
review all FAILED_INTERNAL_ERROR cases and add appropriate logging as needed.
