Date Thu, 28 Mar 2013 01:25:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8205?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13615953#comment-13615953

Jean-Marc Spaggiari commented on HBASE-8205:
--------------------------------------------

I gave it a quick look, and it sound good to me. Does it worth it to add a test for TableLockManager.readLock
too?

> Table locks have been introduced in HBASE-7305, HBASE-7546, and others (see the design
doc at HBASE-7305). 
> This issue adds support in HBCK to report and fix possible conditions about table locks.
Namely, if due to some bug, the table lock remains not-released, then HBCK should be able
to report it, and remove the lock, so that normal table operations will continue. 
> Also see the comments in HBASE-7977.
