Date Fri, 02 Apr 2010 16:56:13 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hbase/FrequentlySeenErrors" page has been changed by DavidButtler.
http://wiki.apache.org/hadoop/Hbase/FrequentlySeenErrors

--------------------------------------------------

New page:
This page lists frequently seen errors in log files.

= HMaster Log =
 * '''ulimit -n 1024'''
An HBase table of any size is going to need more than this.  Current suggestions is to up
this to 36K. See [[Hbase/FAQ#A6|FAQ]]
 
 * '''127.0.0.1'''  
If you are running a distributed HBase system and are still seeing this in your log, then
you need to fix your host resolution.  See [[Hbase/Troubleshooting#A1|TroubleShooting]]
