Subject How can I be able to balance the disk?
Date Fri, 07 Nov 2014 02:26:15 GMT
My Hadoop Cluster Version
Hadoop 1.1.2, Hadoop 2.4.1
 
The disk usage of a datanode is unbalanced. 
I guess that the cause is due to the amount of 100% of disk problems. 
example ) 
/disk01 100%
/disk02 45%
/disk03 70%
 
My guess is that correct? 
If so, How can I be able to balance the disk?
