Hbase procedure

Hello

I was exploring namespace in hbasse and suddenly saw there is something
called as hbaseadmin.execProcedure(.......);
The comment is it is a globally barrier distributed stored procedure.

Can I take some one help me to find Is this similar to rdbms stored proc?

Or any inputs where can be used in client application.

The procedure in this context is different from RDBMS stored procedure.
In flush(), you would see:

    execProcedure("flush-table-proc", tableName.getNameAsString(),

      new HashMap<String, String>());

In MasterFlushTableProcedureManager.java :

  public static final String FLUSH_TABLE_PROCEDURE_SIGNATURE =
"flush-table-proc";

The above is returned by getProcedureSignature().

See the javadoc for MasterProcedureManager to get some idea of what
globally barriered procedures are.

FYI
