Method Detail

preSnapshot

public void preSnapshot(ObserverContext<MasterCoprocessorEnvironment> ctx,
                        HBaseProtos.SnapshotDescription snapshot,
                        HTableDescriptor hTableDescriptor)
                 throws IOException

Description copied from interface: MasterObserver

Called before a new snapshot is taken. Called as part of snapshot RPC call. It can't bypass the default action, e.g., ctx.bypass() won't have effect.

Specified by:

preSnapshot in interface MasterObserver

Overrides:

preSnapshot in class BaseMasterObserver

Parameters:

ctx - the environment to interact with the framework and master

snapshot - the SnapshotDescriptor for the snapshot

hTableDescriptor - the hTableDescriptor of the table to snapshot

Throws:

IOException

preCloneSnapshot

public void preCloneSnapshot(ObserverContext<MasterCoprocessorEnvironment> ctx,
                             HBaseProtos.SnapshotDescription snapshot,
                             HTableDescriptor hTableDescriptor)
                      throws IOException

Description copied from interface: MasterObserver

Called before a snapshot is cloned. Called as part of restoreSnapshot RPC call. It can't bypass the default action, e.g., ctx.bypass() won't have effect.

Specified by:

preCloneSnapshot in interface MasterObserver

Overrides:

preCloneSnapshot in class BaseMasterObserver

Parameters:

ctx - the environment to interact with the framework and master

snapshot - the SnapshotDescriptor for the snapshot

hTableDescriptor - the hTableDescriptor of the table to create

Throws:

IOException
