Jesse Yates commented on HBASE-7841:
------------------------------------
Sure, that will cut down a little bit on the namenode. But this adds a lot more
complication and overhead in terms of starting all these threads and a thread
pool (which seems even more wasteful on a per-snapshot basis). How much perf
does this really gain us??
