IOE ignored during flush-on-close causes dataloss
-------------------------------------------------
Key: HBASE-4270
URL: https://issues.apache.org/jira/browse/HBASE-4270
Project: HBase
Issue Type: Bug
Components: regionserver
Affects Versions: 0.90.4, 0.92.0
Reporter: Todd Lipcon
Priority: Blocker
Fix For: 0.92.0
If the RS experiences an exception during the flush of a region while closing
it, it currently catches the exception, logs a warning, and keeps going. If the
exception was a DroppedSnapshotException, this means that it will silently drop
any data that was in memstore when the region was closed.
Instead, the RS should do a hard abort so that its logs will be replayed.
