Duo Zhang updated HBASE-19095:
------------------------------
Release Note:
Add 4 methods in RegionObserver:
preMemStoreCompaction
preMemStoreCompactionCompactScannerOpen
preMemStoreCompactionCompact
postMemStoreCompaction
preMemStoreCompaction and postMemStoreCompaction will always be called for all
in memory compactions. Under eager mode,
preMemStoreCompactionCompactScannerOpen will be called before opening store
scanner to allow you changing the max versions and TTL, and
preMemStoreCompactionCompact will be called after the creation to let you do
wrapping.
