[GitHub] [hadoop] ashutoshcipher opened a new pull request, #5014: MAPREDUCE-5608. Replace and deprecate mapred.tasktracker.indexcache.mb

ashutoshcipher opened a new pull request, #5014:
URL: https://github.com/apache/hadoop/pull/5014

   ### Description of PR
   
   Replace and deprecate mapred.tasktracker.indexcache.mb
   
   In MR2 mapred.tasktracker.indexcache.mb still works for configuring the size of the shuffle service index cache. As the tasktracker no longer exists, we should replace this with something like mapreduce.reduce.shuffle.indexcache.mb. 
   
   
   ### How was this patch tested?
   UT
   
   
   ### For code changes:
   
   - [X] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
   - [ ] Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
   - [ ] If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under [ASF 2.0](http://www.apache.org/legal/resolved.html#category-a)?
   - [ ] If applicable, have you updated the `LICENSE`, `LICENSE-binary`, `NOTICE-binary` files?

Review Comment:
   Could you make it public static final to be consistent with other parameters?

   Checkstyle in latest Yetus can be ignored as `public static final` is added to keep it consistent with other parameters.
