Method Detail

preAddColumnHandler

public void preAddColumnHandler(ObserverContext<MasterCoprocessorEnvironment> ctx,
                                TableName tableName,
                                HColumnDescriptor column)
                         throws IOException

Description copied from interface: MasterObserver

Called prior to adding a new column family to the table. Called as part of add column handler.

Specified by:

preAddColumnHandler in interface MasterObserver

Overrides:

preAddColumnHandler in class BaseMasterObserver

Parameters:

ctx - the environment to interact with the framework and master

tableName - the name of the table

column - the HColumnDescriptor

Throws:

IOException

postAddColumnHandler

public void postAddColumnHandler(ObserverContext<MasterCoprocessorEnvironment> ctx,
                                 TableName tableName,
                                 HColumnDescriptor column)
                          throws IOException

Description copied from interface: MasterObserver

Called after the new column family has been created. Called as part of add column handler.

Specified by:
