Hi Meena,

I can't pin point the exact problem, but there are two possible
scenarios leading to this issues.

1. Is there may be a mismatch of the hadoop jar file between your
Hadoop cluster and the hadoop jar file in
CHUKWA_HOME/share/chukwa/lib.  By default, Chukwa is shipped with
hadoop-core-1.0.0.jar.  You should replace hadoop-*.jar with the
0.20.205 jar files, then restart the collector.

2. Is your cluster running with Kerberos security turn on?  If yes,
make sure you have the proper core-site.xml in Chukwa classpath and
users keytabs setup.  kinit has been initialized for the Chukwa user.

regards,
Eric
