[HOD] Split the operations of allocation from provisioning in HOD.
------------------------------------------------------------------

Key: HADOOP-2850
URL: https://issues.apache.org/jira/browse/HADOOP-2850
Project: Hadoop Core
Issue Type: Bug
Components: contrib/hod
Affects Versions: 0.16.0
Reporter: Hemanth Yamijala
Assignee: Hemanth Yamijala
Fix For: 0.17.0


Currently, the HOD allocation operation does the following distinct steps - allocate a requested number of nodes, [optionally] transfer a hadoop tarball and install it, then provision hadoop by bringing up the appropriate daemons. It would be nice to separate these layers so each of them could be done independently.

This would lead to a very great flexibility in users using the cluster. For e.g. one could allocate a certain number of nodes, then have hod bring up one version, then bring it down, then repeat this again and so on.

    Nigel Daley commented on HADOOP-2850:
    -------------------------------------

    +1 for this issue. This would effectively make the allocate a pure front for qsub. Of course, for most users, allocate and bringing up the daemons in a single step is what they'll want. That should still be made easy for them (a single command line arg perhaps).
