Manikandan R commented on YARN-4175:
------------------------------------

I tried to use this patch to see if i can add more test cases for YARN-5590 with additional support from YARN-7242. I did the following to make this patch usable:
 # As [~asuresh] mentioned earlier, modified this patch to make use of UpdateContainer API's to update containers. Also ensured variables reflect the same in the code. However, retained the same shell arguments.
 2. Had come to know that YARN-7242 doesn't take care of resource types units from shell arguments. It expects value of type long only and it works based on that. Made changes to pass resource types with units and the same would be considered for further process. But, it converts the value to "Mi" as of now. Ideally, it has to be converted based on server side RM config (Something similar to YARN-7159) . For example, If resource type 'resource1' unit is 'Gi' configured at RM config and clients are passing values in different units, it has to be converted to 'Gi' not to 'Mi'. Thoughts? I can raise a separate JIRA to handle this separately based on comments.
 3. As intent is to add more test cases for YARN-5590, did the same to ensure containers can be updated using distributed shell both in junits and local pseudo set up. I can separate out the patch specific to YARN-5590 changes if needed.
