Subject [jira] Commented: (HADOOP-1887) ArrayIndexOutOfBoundsException with trunk
Date Wed, 12 Sep 2007 23:00:46 GMT

Raghu Angadi commented on HADOOP-1887:
--------------------------------------

The trunk I had was not the latest and was not entirely clean. Since this is so easy to reproduce,
I didn't attach initially. Now I cleaned up my source and updated to latest trunk. The trace
from the latest trunk :

>          Issue Type: Bug
>          Components: dfs
>            Reporter: Raghu Angadi
>
> How to reproduce : 
> # Run a DFS cluster (single node is fine). 
> # Start writing a file but do not close it : {{cat | bin/hadoop dfs -copyFromLocal -
/dir/file}} does that.
> # goto /dir on Hadoop webui or do {{bin/hadoop fs -cat /dir/file}}.
> This is mostly related to HADOOP-1708.
