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).
> [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.
