[jira] [Commented] (HBASE-7848) Use ZK-based read/write lock to make flush-type snapshot robust

["Enis Soztutar (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-7848?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13590051#comment-13590051 ] 

Enis Soztutar commented on HBASE-7848:
--------------------------------------

bq. It seems that all table ops currently take the write lock but I think we'll just need the read table lock
I think you would really need a write lock. 

Patch looks good, except:
{code}
     conf.set(HConstants.HBASE_REGION_SPLIT_POLICY_KEY,
-      ConstantSizeRegionSplitPolicy.class.getName());
+      ConstantSizeRegionSplitPolicy.class.getName()); */
{code}
Can you remove these completely instead of commenting out.
