Subject [jira] [Commented] (HBASE-16744) Procedure V2 - Lock procedures to allow clients to acquire locks on tables/namespaces/regions
Date Wed, 11 Jan 2017 22:56:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-16744?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15819451#comment-15819451

stack commented on HBASE-16744:

Ok. Home stretch. -018 incorporates review from:


though 018 is posted at https://reviews.apache.org/r/55366/

See release note for how to use this new locking 'service' that is for internal consumers
such as MOB and HBCK only; hence it being done as independent LockService as opposed to extending
AdminService (It is not an Endpoint because it a required service, not an appendage).

Any chance of review [~syuanjiang] and [~appy] ? Next up is trying to move off zk and on to
this new locking service ([~jingcheng.du] is helping out w/ MOB piece).
