> Key: MAPREDUCE-7309
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-7309
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Components: applicationmaster
> Affects Versions: 3.0.0, 3.1.0, 3.2.0, 3.3.0
> Reporter: Wangda Tan
> Assignee: Wangda Tan
> Priority: Major
> Attachments: MAPREDUCE-7309.001.patch

>
> This is an issue could affect all the releases which includes YARN-6927.
> Basically, we use regex match repeatly when we read mapper/reducer resource request from config files. When we have large config file, and large number of splits, it could take a long time.
> We saw AM could take hours to parse config when we have 200k+ splits, with a large config file (hundreds of kbs).
> We should do proper caching for pre-configured resource requests.
