Subject Re: hicc error "Error in loading dashboard"
Date Wed, 27 Jun 2012 14:57:28 GMT
Hi,

It looks like HICC rest API can not access /chukwa/hicc/views/*.  
Make sure that HDFS is read/writable for HICC.  There are two possibilities, either Hadoop
conf dir is not defend in chukwa-env.sh or the file permission of HDFS is not setup for chukwa
user.
