Subject [jira] [Commented] (YARN-7941) Transitive dependencies for component are not resolved
Date Mon, 09 Apr 2018 17:36:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7941?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16430939#comment-16430939

Billie Rinaldi commented on YARN-7941:
--------------------------------------

I think I see the problem. The dependency readiness evaluation is checking whether the number
of ready containers equals the number of desired containers. But the number of desired containers
is not being set until a flex event is issued for the component, so we are checking that the
number of ready containers is not less than 0. I think we can fix this by initializing the
number of desired containers in the Component constructor.

> It is observed that transitive dependencies are not resolved as a result one of the component
is started earlier. 
> Ex : In HBase app, 
> master is independent component, 
> regionserver is depends on master.  
> hbaseclient depends on regionserver, 
> but I always see that HBaseClient is launched before regionserver.
