------------------------------------------
Summary: Procedure V2: Support acquire/release shared table lock
concurrently
Key: HBASE-16233
URL: https://issues.apache.org/jira/browse/HBASE-16233
Project: HBase
Issue Type: Sub-task
Components: proc-v2
Reporter: Stephen Yuan Jiang
Assignee: Stephen Yuan Jiang
{{MasterProcedureScheduler.TableQueue}} class only has one single instance of
TableLock ({{private TableLock tableLock = null;}}) to track exclusive/shared
table lock from TableLockManager.
When multiple shared lock request comes, the later shared lock request would
overwrite the lock acquired from earlier shared lock request, and hence, we
will get some weird error when the second or later release lock request comes,
because we lose track of the lock.
