[jira] [Created] (HBASE-7305) ZK based Read/Write locks for table operations

Enis Soztutar created HBASE-7305:
------------------------------------

             Summary: ZK based Read/Write locks for table operations
                 Key: HBASE-7305
                 URL: https://issues.apache.org/jira/browse/HBASE-7305
             Project: HBase
          Issue Type: Bug
          Components: Client, master, Zookeeper
            Reporter: Enis Soztutar
            Assignee: Enis Soztutar
             Fix For: 0.96.0


This has started as forward porting of HBASE-5494 and HBASE-5991 from the 89-fb branch to trunk, but diverged enough to have it's own issue. 

The idea is to implement a zk based read/write lock per table. Master initiated operations should get the write lock, and region operations (region split, moving, balance?, etc) acquire a shared read lock.
