Subject Re: HICC configuration issue
Date Mon, 22 Aug 2011 15:42:36 GMT
TableCreator and DataExpiration utilities are not able to create database tables or drop existing
partitions.  This may be caused by missing mysql connector jar file (we can't bundle this
jar due to license incompatible with ASF).  You will need to manually copy mysql connector
jar file to CHUKWA_HOME/lib.  In addition, make sure CHUKWA_HOME/conf/jdbc.properties is setup
correctly.

regards,
Eric

up the collector, and I have not had version mismatch errors in my namenode log since then.
 I deleted  /chukwa on HDFS and recompiled the fix for CHUKWA-543.  I am running dbAdmin.sh
in the background on the same machine as hicc and I am now getting this error message.  I
am still getting "No Data Available" in HICC. Any thoughts?
