Subject [jira] [Commented] (YARN-9694) UI always show default-rack for all the nodes while running SLS.
Date Mon, 29 Jul 2019 22:49:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-9694?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16895637#comment-16895637

Abhishek Modi commented on YARN-9694:

Thanks [~elgoiri] for reviewing it.

GenerateNodeTableMapping generates a node to rack mapping file which is then being used by
TableMapping to resolve rack names. The format required by TableMapping is a two column text
file where first column specifies node name and second column specifies rack name. I am generating
this file as part of generateNodeTableMapping.


May be I will remove the format name from the file. Will upload an updated patch with changing
the format and having better javadoc.

always shows that rack of the node is default-rack.
