Description




Add new
 column
s into web UI:
– Block
Pool
Used
the storage used for the block pool


-- Block
Pool
Used
%

% of total storage used for that DN for the block pool.

1. Uses DFSUtil for percent calculation. Note that JSP had a bug where it reported, when total was 0, percent used as 0 and percent remaining as 100. Rest of the code in namenode node report percent used as 100 and remaining as 0 when total is 0.
2. Updated documentation ClientProtocol.getStats() method to reflect the new usage info
