Vinayakumar B commented on HDFS-6292:
-------------------------------------
Good one Ravi.
I think calculating in Secondary NN side is OK. But I have a feeling like,
just to get these statistics user needs to navigate to SNN page is not a good
idea.
How about keeping track of these in NameNode side from the starting itself and
update these statistics (same as other metrics.) for every operation which
modifies these and avoid re-calculation of whole statistics in between to avoid
holding namesystem lock for more time.
