------------------------------
Summary: Add observer notification before bulk loaded hfile is
moved to region directory
Key: HBASE-17292
URL: https://issues.apache.org/jira/browse/HBASE-17292
Project: HBase
Issue Type: Improvement
Reporter: Ted Yu
Assignee: Ted Yu
Currently the postBulkLoadHFile() hook notifies the locations of bulk loaded
hfiles.
However, if bulk load fails after hfile is moved to region directory but before
postBulkLoadHFile() hook is called, there is no way for pluggable components
(replication, backup / restore) to know which hfile(s) have been moved to
region directory.
This issue adds a preCommitStoreFile() hook which notifies path of to be
committed hfile before bulk loaded hfile is moved to region directory.
