------------------------------------
Summary: Improve copy snapshot manifest in ExportSnapshot
Key: HBASE-20579
URL: https://issues.apache.org/jira/browse/HBASE-20579
Project: HBase
Issue Type: Improvement
Components: mapreduce
Affects Versions: hbase-2.0.0-alpha-4
Reporter: Jingyun Tian
Assignee: Jingyun Tian
Fix For: hbase-2.0.0-alpha-4
ExportSnapshot need to copy snapshot manifest to destination cluster first,
then setOwner and setPermission for those paths. But it's done with one thread,
which lead to a long time to submit the job if your snapshot is big. I tried to
make them processing in parallel, which can reduce the total time of submitting
dramatically.
