List of startRegionOperation() Examples

Examples of startRegionOperation()

org.apache.hadoop.hbase.regionserver.HRegion.startRegionOperation()
This method needs to be called before any public call that reads or modifies data. It has to be called just before a try. #closeRegionOperation needs to be called in the try's finally block Acquires a read lock and checks if the region is closing or closed. @throws NotServingRegionException when the region is closing or closed @throws RegionTooBusyException if failed to get the lock in time @throws InterruptedIOException if interrupted while waiting for a lock
