Subject [jira] [Commented] (HBASE-5826) Improve sync of HLog edits
Date Thu, 17 May 2012 16:24:06 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13277937#comment-13277937
] 

Zhihong Yu commented on HBASE-5826:
-----------------------------------

@Todd:
Were you referring to the following code ?
{code}
+    synchronized void waitForSync(long txid) throws InterruptedException {
+      while (syncedTillHere < txid) {
+        wait();
+      }
+    }
{code}
It turns out that the above method is never referenced.

See patch v4 where it is removed.
