stack commented on HBASE-15506:
-------------------------------
HDFS-7276 adds 4 new configs (5 including the enable) where you adjust the
manager to suit loading. A bit of work to figure good defaults that make it so
this feature a benefit rather than a drawback would help this issue along;
would be great if it ergonomically adjusted to the loading rather than require
manual adjustment. We'd probably be first users too so some long running tests
with this enabled would help this issue too (were some interesting issues
during its development/testing).
