NPE in TaskLogAppender

[aaron morton]

I'm running the Cassandra Brisk server with Haddop core 20.203 on OSX, 
everything is local. 

I keep running into this problem for Hive jobs

 INFO 13:52:39,923 Error from attempt_201108151342_0001_m_000001_1: 
java.lang.NullPointerException
        at 
org.apache.hadoop.mapred.TaskLogAppender.flush(TaskLogAppender.java:67)

org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1059)
        at org.apache.hadoop.mapred.Child.main(Child.java:253)

The only info I've found online was 
http://www.mail-archive.com/common-user@hadoop.apache.org/msg12829.html

Just for fun I tried…
* setting mapred.acls.enabled to true 
* setting mapred.queue.default.acl-submit-job and 
mapred.queue.default.acl-administer-jobs to *

There was no discernible increase in joy though. 

 Any thoughts ? 

Cheers
