Method Detail

preDeleteTable

public void preDeleteTable(ObserverContext<MasterCoprocessorEnvironment> ctx,
                           TableName tableName)
                    throws IOException

Description copied from interface: MasterObserver

Called before HMaster deletes a table. Called as part of delete table RPC call. It can't bypass the default action, e.g., ctx.bypass() won't have effect.

Specified by:

preDeleteTable in interface MasterObserver

Overrides:

preDeleteTable in class BaseMasterObserver

Parameters:

ctx - the environment to interact with the framework and master

tableName - the name of the table

Throws:

IOException

postDeleteTableHandler

public void postDeleteTableHandler(ObserverContext<MasterCoprocessorEnvironment> ctx,
                                   TableName tableName)
                            throws IOException

Description copied from interface: MasterObserver

Called after HMaster deletes a table. Called as part of delete table handler and it is async to the delete RPC call. It can't bypass the default action, e.g., ctx.bypass() won't have effect.

Specified by:

postDeleteTableHandler in interface MasterObserver

Overrides:

postDeleteTableHandler in class BaseMasterObserver

Parameters:

ctx - the environment to interact with the framework and master

tableName - the name of the table

Throws:

IOException

preCreateTable

public void preCreateTable(ObserverContext<MasterCoprocessorEnvironment> ctx,
                           HTableDescriptor desc,
                           HRegionInfo[] regions)
                    throws IOException

Description copied from interface: MasterObserver

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

Specified by:

preCreateTable in interface MasterObserver

Overrides:

preCreateTable in class BaseMasterObserver

Parameters:

ctx - the environment to interact with the framework and master

desc - the HTableDescriptor for the table

regions - the initial regions created for the table

Throws:

IOException
