Subject [jira] [Commented] (HBASE-15264) Implement a fan out HDFS OutputStream
Date Fri, 19 Feb 2016 09:03:18 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15264?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15153951#comment-15153951

Duo Zhang commented on HBASE-15264:

Oh, I forgot an important thing, we can not close WAL writer asynchronously and also we can
not use recoverFileLease.

The reason is that, we use the lease on WAL file to do fencing, which means that, if we failed
to close the WAL file current being written , it is likely that we are considered dead on

So the close must be synchronous, and also, we should close the file normally instead of calling

Let me retry the recoverAndClose part...
