exception related to logging (using latest sources)

Hi

I am getting following exception when running map-reduce jobs.


java.lang.NullPointerException
	at  
org.apache.hadoop.mapred.TaskLogAppender.flush(TaskLogAppender.java:69)
	at org.apache.hadoop.mapred.TaskLog.syncLogs(TaskLog.java:222)
	at org.apache.hadoop.mapred.Child$4.run(Child.java:219)
	at java.security.AccessController.doPrivileged(Native Method)
	at javax.security.auth.Subject.doAs(Subject.java:396)

org 
.apache 
.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java: 
813)
	at org.apache.hadoop.mapred.Child.main(Child.java:211)


I am using latest sources (0.22.0-snapshot) that I have built myself.

any ideas?

thanks
