Subject [jira] [Created] (HBASE-16685) Revisit execution of SnapshotCopy in MapReduceBackupCopyService
Date Thu, 22 Sep 2016 18:11:20 GMT
Ted Yu created HBASE-16685:
------------------------------

             Summary: Revisit execution of SnapshotCopy in MapReduceBackupCopyService
                 Key: HBASE-16685
                 URL: https://issues.apache.org/jira/browse/HBASE-16685
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


During code review of backup / restore, Matteo raised comment on the following code:
{code}
        res = snapshotCp.run(options);
{code}
I think this will be a first time where HBase server has a direct dependency on a MR job.

also we need to revisit this code to avoid having one handler blocked for N hours while we
are doing a copy.

This issue is to address the above comment.
