Zhijie Shen commented on YARN-956:
----------------------------------
Did some similar local tests for 1 application, 1 attempt and multiple
container as I did for YARN-975. The memory occupancy is summarized bellow:
| \# of containers | 0 | 100 | 1000 | 10K | 100K |
| memory | 67MB | 68MB | 71MB | 81MB | 139MB |
No that even no data is put into the in-memory store, JVM still gave 67MB for
this process to run.
