-------------------------------------
Summary: Document risks of RegionObserver.preStoreScannerOpen
Key: HBASE-19534
URL: https://issues.apache.org/jira/browse/HBASE-19534
Project: HBase
Issue Type: Bug
Reporter: Lars Hofhansl
Assignee: Lars Hofhansl
We just had an outage because we used preStoreScannerOpen, which, in our case,
created a new StoreScanner. In HBase versions before 1.3 this caused a definite
memory leak, a reference to the old StoreScanner (if not null) would be held by
the store until the region is closed.
The 1.3 and later there's no such leak, but still the old scanner is not
properly closed.
This should be added to the Javadoc and the ZooKeeperScanPolicyObserver example
should be fixed.
