> Key: YARN-6810
> URL: https://issues.apache.org/jira/browse/YARN-6810
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 2.7.3
> Reporter: Prabhu Joseph
>
> When a localized mapreduce.tar.gz is corrupt and zero bytes, all MapReduce
> jobs fails on the cluster with "Error: Could not find or load main class
> org.apache.hadoop.mapreduce.v2.app.MRAppMaster " as it uses corrupt
> mapreduce.tar.gz. YARN Localizer has to check if the existing
> mapreduce.tar.gz is a valid file before using it.
