Stephen Yuan Jiang commented on HBASE-15371:
--------------------------------------------

[~tedyu], once parent procedures submit child procedures and finish his step, he would sleep
and wait for child procedure to complete.  At that time, no new child procedures would be
added for this parent procedure.

> In Procedure-V2 Phase 1 (HBASE-14336), some infrastructure of supporting child procedure
exists.  However, there is no need in Phase 1 (master DDL) to have multi-level procedures.
 This JIRA implements adding child procedures to procedure execution list and execute them
before parent procedure can make further progress.
