Subject [jira] [Commented] (YARN-7129) Application Catalog for YARN applications
Date Fri, 22 Mar 2019 03:31:00 GMT

    [ https://issues.apache.org/jira/browse/YARN-7129?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16798680#comment-16798680
] 

Eric Yang commented on YARN-7129:
---------------------------------

[~jeagles] Solr dependencies runs in the application catalog docker container.  There is no
solr dependencies added to any Hadoop services.  Hence, no interference to customer's applications.

{quote}In addition, I see this patch adds another class named YarnClient. Is there a way to
name this class differently to remove this conflation?{quote}

This is not the first time that Yarn uses the same class name in different packages.  YarnClient
is already prefixed with different packages name.  This class runs in a isolated JVM in YARN
framework.  The chance of other people getting it wrong is low because the other YarnClient
is abstract and private api.  I highly doubt YarnClient is going to cause a problem, but I
can call it YarnServiceClient to make the distinction.

> YARN native services provides web services API to improve usability of application deployment
on Hadoop using collection of docker images.  It would be nice to have an application catalog
system which provides an editorial and search interface for YARN applications.  This improves
usability of YARN for manage the life cycle of applications.
