> ScriptBasedMapping has infinite loop with invalid jobconf parameter
> -------------------------------------------------------------------
>
> Key: HADOOP-4141
> URL: https://issues.apache.org/jira/browse/HADOOP-4141
> Project: Hadoop Core
> Issue Type: Bug
> Affects Versions: 0.18.1
> Reporter: Aaron Kimball
> Priority: Minor
> Attachments: HADOOP-4141.patch.3, scriptMap.patch, scriptMap.patch.2,
> TestScriptBasedMapping.java
>
> Original Estimate: 0h
> Remaining Estimate: 0h
>
> A few bugs in ScriptBasedTopology:
> 1) topology.script.number.args is not validated; if this is <= 0, the
> runResolveCommand() method will run its outer loop an infinite number of
> times.
> 2) CachedDNSToSwitchMapping assumes that if a List is returned, it has the
> same cardinality as the number of names. ScriptBasedMapping should return
> 'null' instead of a mis-sized list on error
