Method Detail

postCompleteSplit

public void postCompleteSplit(ObserverContext<RegionCoprocessorEnvironment> ctx)
                       throws IOException

Description copied from interface: RegionObserver

Called after any split request is processed. This will be called irrespective of success or failure of the split.

Specified by:

postCompleteSplit in interface RegionObserver

Overrides:

postCompleteSplit in class BaseRegionObserver

Throws:

IOException

postCompact

public void postCompact(ObserverContext<RegionCoprocessorEnvironment> e,
                        Store store,
                        StoreFile resultFile)
                 throws IOException

Description copied from interface: RegionObserver

Called after compaction has completed and the new store file has been moved in to place.

Specified by:

postCompact in interface RegionObserver

Overrides:

postCompact in class BaseRegionObserver

Parameters:

e - the environment provided by the region server

store - the store being compacted

resultFile - the new store file written out during compaction

Throws:

IOException - if an error occurred on the coprocessor

preSplitBeforePONR

public void preSplitBeforePONR(ObserverContext<RegionCoprocessorEnvironment> ctx,
                               byte[] splitKey,
                               List<Mutation> metaEntries)
                        throws IOException

Description copied from interface: RegionObserver

This will be called before PONR step as part of split transaction. Calling ObserverContext.bypass() rollback the split

Specified by:

preSplitBeforePONR in interface RegionObserver

Overrides:

preSplitBeforePONR in class BaseRegionObserver

Throws:

IOException

start

public void start(CoprocessorEnvironment e)
           throws IOException

Specified by:

start in interface Coprocessor

Overrides:

start in class BaseRegionObserver

Throws:

IOException
