Vinod K V commented on MAPREDUCE-1218:
--------------------------------------
bq. I have found that there is a mistake in the previous patch. Previously I
made MemoryCalculatorPlugin extends ResourceCalculatorPlugin and
LinuxMemoryCalculatorPlugin extends LinuxResourceCalculatorPlugin. But
LinuxResourceCalculatorPlugin does not extend MemoryCalculatorPlugin.
Good catch!
{{DummyMemoryCalculatorPlugin}} needs to be deprecated still?. Other than that,
+1 for the patch.
Once that is done, and after Hudson blesses it, can you ask someone to commit
this? Thanks for being patient!
