Subject Not Starting Hmaster bacause of Permission denied
Date Fri, 19 Aug 2011 07:32:41 GMT
Hi All,
I am facing an issue to start Hmaster bacause of Permission denied,
although two region servers seem start properly. I will be much
appreciated if any one could help me to figure out the root cause. I
have hadoop running under 'hadoop' user, and Hbase running under 'hbase'
user. Thanks, - Andy Zhong
