Subject [jira] [Commented] (HBASE-8065) the bulkload can load the hfile into hbase table,but this mechanism can't remove the date before
Date Mon, 11 Mar 2013 18:37:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13599104#comment-13599104
] 

Ted Yu commented on HBASE-8065:
-------------------------------

{code}
+   * @param familyPaths List of Pair<byte[] column family, String hfilePath>
{code}
In javadoc, there is no need to mention parameter names.
{code}
+    this.lock.writeLock().lock();
+    this.lock.readLock().lock();
{code}
Why are the write/read locks taken consecutively ?
