[jira] [Commented] (HBASE-21577) do not close regions when RS is dying due to a broken WAL

    [ https://issues.apache.org/jira/browse/HBASE-21577?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16715996#comment-16715996 ] 

Duo Zhang commented on HBASE-21577:
-----------------------------------

Is it possible to just set fsOk to false when there is a DroppedSnapshotException?

> See HBASE-21576. DroppedSnapshot can be an FS failure; also, when WAL is broken, some regions whose flushes are already in flight keep retrying, resulting in minutes-long shutdown times. Since WAL will be replayed anyway flushing regions doesn't provide much benefit.
