safemode forever

Hi,
  I'm wondering if anyone has solutions about the nonstopped safe mode, any
way to get it around?

  thanks,

error: org.apache.hadoop.dfs.SafeModeException: Cannot delete
/mapred/system. Name node is in safe mode.
The ratio of reported blocks 0.4696 has not reached the threshold 0.9990.
Safe mode will be turned off automatically.

It means tht not all blocks have been reported
Can u check how many datanodes have reported in UI or bin/hadoop 
dfsadmin -report

In case u have to disable the safemode check bin/hadoop dfsadmin 
-safemode command
it has options to enter/leave/get
