Lars Hofhansl commented on HBASE-14098:
---------------------------------------
That makes sense. Thanks [~eclark]. A cheap approximation might be to set it
for major compactions. Agree that ideally we'd decided based on the size of the
output file(s) compared to the available RAM for the OS buffer cache.
> Allow dropping caches behind compactions
