Vinod Kumar Vavilapalli commented on YARN-5021:
-----------------------------------------------
There are many cases where ProcfsBasedProcessTree (which I am assuming is what
getting used, assuming Linux) returns UNAVAILABLE (-1 as a value).
Unfortunately we don't have enough logs in the code to identify those
scenarios. Can you run "getconf CLK_TCK" and "getconf "PAGESIZE" on your box
and paste the values here?
