Phabricator updated HBASE-5033:
-------------------------------
Attachment: D933.1.patch
Liyin requested code review of "[jira][HBASE-5033][[89-fb]]Opening/Closing
store in parallel to reduce region open/close time".
Reviewers: Kannan, mbautin, Karthik, JIRA
Region servers are opening/closing each store and each store file for every
store in sequential fashion, which may cause inefficiency to open/close regions.
So this diff is to open/close each store in parallel in order to reduce
region open/close time. Also it would help to reduce the cluster restart time.
1) Opening each store in parallel
2) Loading each store file for every store in parallel
3) Closing each store in parallel
4) Closing each store file for every store in parallel.
TEST PLAN
1) Running all the unit tests
2) Test it on dev cluster to see how much time saved by close/open region in
parallel when restart the cluster.
