Re: Re: hicc error "Error in loading dashboard"
Hi Eric,

I removed the folder hicc in hdfs and restarted hicc, then it worked.
Now it complains "java.text.ParseException: java.lang.NullPointerException " at org.apache.hadoop.chukwa.rest.bean.WidgetBean.<init>(WidgetBean.java:55), and i think it should because of no record in hbase tables. i will test more about this.

Thanks very much and best regards to you!

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.

Hi all,

Any suggestions about this? Thanks very much.
