Lars Hofhansl commented on HBASE-7638:
--------------------------------------
With HBASE-7268 not fixed in 0.94. Is it possible to we now hold on to an old
stale cache entry (produced as described in HBASE-7268), where before this
patch we'd clean the cache (even if done too eagerly)?
That would possibly explain why we see tests only fail sometimes (it would have
to run into that scenario).
I think I am going to revert this from 0.94 for now. The performance
optimization from this should be slight (if any?) Please let me know if you
disagree?
