Constructor Detail

DisabledTableSnapshotHandler

public DisabledTableSnapshotHandler(HBaseProtos.SnapshotDescription snapshot,
                                    MasterServices masterServices)

Parameters:

snapshot - descriptor of the snapshot to take

masterServices - master services provider

Method Detail

prepare

public DisabledTableSnapshotHandler prepare()
                                     throws java.lang.Exception

Description copied from class: EventHandler

Event handlers should do all the necessary checks in this method (rather than in the constructor, or in process()) so that the caller, which is mostly executed in the ipc context can fail fast. Process is executed async from the client ipc, so this method gives a quick chance to do some basic checks. Should be called after constructing the EventHandler, and before process().

Overrides:

prepare in class TakeSnapshotHandler

Returns:

the instance of this class

Throws:

java.lang.Exception - when something goes wrong

snapshotRegions

public void snapshotRegions(java.util.List<Pair<HRegionInfo,ServerName>> regionsAndLocations)
                     throws java.io.IOException,
                            KeeperException

Description copied from class: TakeSnapshotHandler

Snapshot the specified regions

Specified by:

snapshotRegions in class TakeSnapshotHandler

Throws:

java.io.IOException

KeeperException
