> {{newFilesNotFromConf}} and tries to access {{newResources.get(i)}} in that.
> Size of {{newResources}} is determined by [utils.localizeTempFiles()
> here|https://github.com/apache/hive/blob/rel/release-3.1.1/ql/src/java/org/apache/hadoop/hive/ql/exec/tez/TezSessionState.java#L629]

> this would result in {{newResources.size()}} < {{newFilesNotFromConf.length}}
> causing IndexOutOfBounds.
