Vladimir Rodionov commented on HBASE-16685: ------------------------------------------- One handler blocked for hours is OK as long as we have 100 of them. I do not see any issue here. I do not mind changing code if it is not a big one though. Master does not have direct dependencies on M/R I think - only on backup package. > 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 > Labels: backup > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
