JobClient hangs-up in getTaskLogs

Hi,

I'm using  two hadoop clusters, 0.21.0 and CDH2.
The problem which resembled MAPREDUCE-1868 by my clusters by hanging up of
TaskTracker occurred.

Is it having to take the following methods in order to solve this problem?
1. The patch contributed by MAPREDUCE-1868 and the similar patch are applied
to 0.21.0 and CDH2.
2. Property "mapreduce.client.output.filter" is changed into "NONE"
(However, FAILED-tasklog disappears from JobClient).

Regards,
