Subject [jira] [Commented] (YARN-5269) Bubble exceptions and errors all the way up the calls, including to clients.
Date Thu, 09 Mar 2017 22:39:38 GMT

    [ https://issues.apache.org/jira/browse/YARN-5269?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15904005#comment-15904005

Vrushali C commented on YARN-5269:
----------------------------------

Let me get back on the questions [~haibochen].  As such we have a flush done every 1 min by
the writerFlusher, defined in TimelineCollectorManager. The default flush interval is 1 min,
configuration via yarn config setting TIMELINE_SERVICE_WRITER_FLUSH_INTERVAL_SECONDS.

Also, whenever a per app collector shuts down, the serviceStop invokes  a flush before closing
the table connection.

> Currently we ignore (swallow) exception from the HBase side in many cases (reads and
writes).
> Also, on the client side, neither TimelineClient#putEntities (the v2 flavor) nor the
#putEntitiesAsync method return any value.
> For the second drop we may want to consider how we properly bubble up exceptions throughout
the write and reader call paths and if we want to return a response in putEntities and some
future kind of result for putEntitiesAsync.
