[jira] [Updated] (HBASE-11296) TableLockManager should provide API
which returns whether specific table has outstanding lock
[ https://issues.apache.org/jira/browse/HBASE-11296?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ted Yu updated HBASE-11296:
---------------------------
Description:
In HBASE-11282, one proposal is to skip region movement during the period when table lock is held on the underlying table.
Currently TableLockManager provides the following API which iterates through all locks:
{code}
public void visitAllLocks(MetadataHandler handler) throws IOException {
{code}
The above API is heavyweight for this use case where table name is known.
This JIRA is to add new API which returns whether given table has outstanding read / write lock.
