HTable.delete triggers pre/postScannerOpen upcalls of RegionObserver
--------------------------------------------------------------------
Key: HBASE-3758
URL: https://issues.apache.org/jira/browse/HBASE-3758
Project: HBase
Issue Type: Bug
Components: coprocessors
Reporter: Mingjie Lai
Assignee: Mingjie Lai
Fix For: 0.92.0
Currently RegionObserver pre/postScannerOpen() upcalls are injected at
HRegion.instantiateInternalScanner(). If someone uses scanner methods at
HRegion, ScannerOpen upcalls can be triggered unexpectedly. HBase-3583 pulled
scannerNext and scannerClose from HRegion to HRegionServer. We also need to
pull scannerOpen to HRegionObserver to prevent unexpected triggers.
