Subject: Re: How to find extent of data node imbalance ?

Reposting ...

One option is to do "hdfs dfsadmin -report" and see "DFS Used%" on each data 
node and then compute the extent of imbalance across nodes. Is there any other 
way ?

Thanks,

Hi,

Before running hadoop rebalancer, it is possible to find the extent to which 
the data nodes are unbalanced ?
