Subject [jira] Commented: (HBASE-2398) NPE in HLog.append when calling writer.getLength
Date Wed, 31 Mar 2010 23:20:27 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2398?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12852164#action_12852164
] 

Todd Lipcon commented on HBASE-2398:
------------------------------------

If we move the log roll to hflush(), will it actually perform the roll or just trigger it?
It seems bad to put an HDFS create() call on the critical path to a read.

> Doing some test uploads on a fresh single node setup, I'm seeing non-fatal NPEs in the
region server log coming from HLog.append when calling writer.getLength. I'll post a log in
a follow-up comment.
> Assigning to Nicolas so that he takes a look.
