Wangda Tan updated YARN-6620:
-----------------------------
Attachment: YARN-6620.006-WIP.patch
Attached ver.6 WIP patch.
Updates:
1) Switched JAXB to handle XML parsing instead of check tags. ([~devaraj.k]
please review).
2) Discussed with [~tangzhankun] / [~zyluo] / [[email protected]] offline,
Added {{ResourcePlugin}} interface to make future adding new resource types
support to NM could be easier. Minimum code changes of core NM are needed to
support new resource types (like SSD/FPGA).
Please refer to package:
{{org.apache.hadoop.yarn.server.nodemanager.containermanager.resourceplugin}}
TODO:
1) Integration to load/set resource value to {{Resource}} vector after
YARN-3926 merge.
2) Integration to report resource value while registering/updating to NM.
3) Javadocs / unit test / compilation for new added classes / logics.
