[jira] [Updated] (YARN-4986) Add a check in the coprocessor for
table to operated on
[ https://issues.apache.org/jira/browse/YARN-4986?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Vrushali C updated YARN-4986:
-----------------------------
Attachment: YARN-4986-YARN-2928.01.patch
Uploading patch v1. This code will simply "disable" the coprocessor code for any table other than the flow run table.
Also, this patch includes a fix for YARN-5014 . The FlowScanner class is the fix for this patch.
Both taken together have been tested for coprocessor execution on an actual cluster.

> As a precautionary measure, it will be a good idea to have the coprocessor code check which table it needs to be working on and return/proceed accordingly. This is more of a safety check so that we are sure we are not inadvertently executing the coprocessor code on some other table.
