Hi,
I am using Hadoop 1.0.0 and want to try HDFSProxy . Following:
http://hadoop.apache.org/hdfs/docs/r0.21.0/hdfsproxy.html#Jetty-based+Insta=
llation+and+Configuration

When I run start-hdfsproxy.sh script I get following error in logs :
************************************************************/

ava:135)
at org.apache.hadoop.hdfsproxy.HdfsProxy.main(HdfsProxy.java:142)

After googling around I got this Jira "https://issues.apache.org/jira/brows=
e/HADOOP-5432"
Should I apply this patch to fix the issue ?

Please suggest

Regards,
