Hemanth Yamijala updated HADOOP-3483:
-------------------------------------
Status: Patch Available (was: Open)
Simple patch addressing both issues.
Now, we try and create the cluster directory if it doesn't exist. Likewise, if
a cluster becomes dead, and an allocate is tried using the same cluster
directory, we warn the user that the cluster is being deallocated and allocate
a new one using the same directory. No, data in the directory is lost.
> [HOD] Improvements with cluster directory handling
> --------------------------------------------------
>
> Key: HADOOP-3483
> URL: https://issues.apache.org/jira/browse/HADOOP-3483
> Project: Hadoop Core
> Issue Type: Bug
> Affects Versions: 0.16.0
> Reporter: Hemanth Yamijala
> Assignee: Hemanth Yamijala
> Fix For: 0.18.0
>
>
> The following improvements are asked for from users related to cluster
> directory handling:
> - Create a new cluster directory if one does not exist.
> - If a cluster directory points to a dead cluster, currently allocate fails
> with a message asking user to deallocate it first. Instead, it should issue a
> warning, deallocate the cluster and automatically allocate a fresh one.
