Asynchronous table creation
---------------------------
Key: HADOOP-1469
URL: https://issues.apache.org/jira/browse/HADOOP-1469
Project: Hadoop
Issue Type: New Feature
Components: contrib/hbase
Affects Versions: 0.13.0
Reporter: James Kennedy
Priority: Minor
In some of my code i found it efficient to create a new table without
immediately requiring (blocking for) the client to have references to it's
HRegions. Effectively this requires that the client update the table info only
as needed.
Can something like the following method to HClient be added?
/**
* Creates a new table but does not block and wait for it to come
online.
*
* @param desc -
* table descriptor for table
*
* @throws IllegalArgumentException -
* if the table name is reserved
* @throws MasterNotRunningException -
* if master is not running
* @throws NoServerForRegionException -
* if root region is not being served
* @throws IOException
*/
public synchronized void createTableAsync(HTableDescriptor desc)
throws IOException {
checkReservedTableName(desc.getName());
checkMaster();
try {
this.master.createTable(desc);
} catch (RemoteException e) {
handleRemoteException(e);
}
}
which is basically the same as createTable() except without the
findServersForTable(desc.getName()) part.
