Subject chukwa collector crashed because org.apache.hadoop.ipc.RemoteException
Date Mon, 11 Apr 2011 07:18:21 GMT
The log showed
2011-04-07 08:50:17,584 WARN LeaseChecker DFSClient - Problem renewing lease
for DFSClient_-252461351
org.apache.hadoop.ipc.RemoteException:
org.apache.hadoop.hdfs.server.namenode.SafeModeException: Cannot renew lease
for DFSClient_-252461351. Name node is in safe mode.
The reported blocks 31049 needs additional 3088 blocks to reach the
threshold 0.9990 of total blocks 34172. Safe mode will be turned off
automatically.
And the chukwa collector crashed.

Is this problem caused by hadoop or chukwa ?
