Description

Using FileContext to look at the dfs metrics:

dfs.FSNamesystem: hostName=gs301017.inktomisearch.com, sessionId=, BlocksTotal=90, CapacityRemainingGB=3375, CapacityTotalGB=3632, CapacityUsedGB=1, FilesTotal=175, PendingReplicationBlocks=0, ScheduledReplicationBlocks=0, TotalLoad=0, UnderReplicatedBlocks=1
dfs.FSNamesystem: hostName=gs301017.inktomisearch.com, sessionId=, BlocksTotal=90, CapacityRemainingGB=0, CapacityTotalGB=0, CapacityUsedGB=0, FilesTotal=175, PendingReplicationBlocks=0, ScheduledReplicationBlocks=0, TotalLoad=0, UnderReplicatedBlocks=0

Both primary name node and seconddary name nodes are sending out data. However, secondary name node should send 0 instead, since secondary name node is not really being used.
