Subject Re: How to understand DataNode usages ?
Date Fri, 15 Feb 2013 04:10:44 GMT
This seems to be related to the % used capacity at a datanode. The values
are computed for all the live datanodes, and the range / central limits /
deviations are computed based on a sorted list of the values.

Thanks
