Re: HBase Exceptions in HICC
I'm getting the below error when I try to see SystemMetrics in HICC.
I'm using the sigar.SystemMetrics and I also see data in hbase. I got the
latest chukwa from trunk. Any clue what might be wrong?

Re: HBase Exceptions in HICC
Posted by Eric Yang <ey...@yahoo-inc.com>.
I recommend to set the server to UTC to avoid day light saving time issues with data. HICC web server should also run from UTC time server. There is a lot of polish required to get HICC UI to display local time zone correctly. Feel free to file jiras.
Regards,
Eric

Is the server set to UTC timezone? If it is not, you might need to select time range n hours ahead or behind of current time.
In addition, what version is the HBase?

Eric

Re: HBase Exceptions in HICC

Hi abhijit,
I notice that Hbase 0.90.3 returns a null pointer for empty list. This was different from 0.20.6 behavior. As a workaround, set time range to last 1 hour, and see if you still get this exception. Please file a JIRA. Thanks

Eric
