示例1: postCreateTableHandler
import org.apache.hadoop.hbase.security.access.Permission.Action; //导入方法依赖的package包/类
@Override
public void postCreateTableHandler(final ObserverContext<MasterCoprocessorEnvironment> c,
HTableDescriptor desc, HRegionInfo[] regions) throws IOException {
// When AC is used, it should be configured as the 1st CP.
// In Master, the table operations like create, are handled by a Thread pool but the max size
// for this pool is 1. So if multiple CPs create tables on startup, these creations will happen
// sequentially only.
// Related code in HMaster#startServiceThreads
// {code}
// // We depend on there being only one instance of this executor running
// // at a time. To do concurrency, would need fencing of enable/disable of
// // tables.
// this.service.startExecutorService(ExecutorType.MASTER_TABLE_OPERATIONS, 1);
// {code}
// In future if we change this pool to have more threads, then there is a chance for thread,
// creating acl table, getting delayed and by that time another table creation got over and
// this hook is getting called. In such a case, we will need a wait logic here which will
// wait till the acl table is created.
