[jira] Created: (HADOOP-7149) Topology script should have some kind of timeout

Topology script should have some kind of timeout
------------------------------------------------

                 Key: HADOOP-7149
                 URL: https://issues.apache.org/jira/browse/HADOOP-7149
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 0.23.0
            Reporter: Todd Lipcon


We've seen an issue where a custom topology script was hanging for some external reason. This caused the NN to block during startup without any kind of clear indication what was going on.

We should consider adding a timeout for the topology script execution, or at least a timer which triggers WARN or ERROR level messages if it takes longer than a few seconds.
