Lijin Bin commented on HBASE-24372:
-----------------------------------
{code}
/**
* Called after the createTable operation has been requested. Called as part
* of create table RPC call.
* @param ctx the environment to interact with the framework and master
* @param desc the TableDescriptor for the table
* @param regions the initial regions created for the table
*/
default void postCreateTable(final
ObserverContext<MasterCoprocessorEnvironment> ctx,
TableDescriptor desc, RegionInfo[] regions) throws IOException {}
{code}
Looks like the current is ok. We should change RSGroupAdminEndpoint.
> HBASE-20658 Release latch later for CreateTable procedure.
