["Vrushali C (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/YARN-4062?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Vrushali C updated YARN-4062:
-----------------------------
    Attachment: YARN-4062-feature-YARN-2928.02.patch


Uploading patch v2. I have made all the changes suggested by Sangjin.

Only change that has not been made yet is the 

bq. can you add this parameter as a real configuration (in YarnConfiguration.java/yarn-default.xml)?

The reason is that I am trying to figure out how to access the Yarn Configuration variable in the hbase coprocessor. The conf or that specific variable/value needs to be passed around somehow. This setting is from the source hadoop cluster and is to be used on the sink hbase/hadoop cluster.

> As part of YARN-3901, coprocessor and scanner is being added for storing into the flow_run table. It also needs a flush & compaction processing in the coprocessor and perhaps a new scanner to deal with the data during flushing and compaction stages.
