Hi Eric, Thanks for the quick reply.I have tried to install chukwa 0.5 accordingly. but there seems to be a problem while starting chukwa-collector. In the log files i could see something related to hbase. I haven't installed any hbase in my cluster. Therefore I commented out the parameters related to hbase in my chukwa-collector-conf.xml. Is it necessary to have a hbase installation for chukwa 0.5 to work.
