Zhankun Tang commented on YARN-9861:
------------------------------------
[~billie.rinaldi], if any chance, could you please take a look at this?
The issue happens when running the submarine per offline discussion. It seems
caused by yarn native service leaks the socket/hdfs file handles. Thoughts?
> The ResourceManager log reports an error "Too many open files", the analysis
> is related to the service
