Li Lu updated YARN-4851:
------------------------
Attachment: YARN-4851-trunk.004.patch
Version 004 patch to address [~djp]'s comments. One thing to notice is that I
did not directly add the reference to EntityGroupFSTimelineStore in TDM
metrics. Instead, I changed the javadoc of EntityGroupFSTimelineStoreMetric to
make it point to TDM metrics. This is because the ats v1.5 plugin storage is
added as a separate module and depends on the original ATS module. Adding a
link from TDM metrics to EntityGroupFSTimelineStoreMetric requires the ATS v1
module depends on the pluginstorage module, which is counterintuitive (and will
cause cyclic dependencies). So right now I make the main javadoc increments on
the plugin storage side. Please feel free to let me know if there's better way
to organize this. Thanks!
