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. > Bubble exceptions and errors all the way up the calls, including to clients. > ---------------------------------------------------------------------------- > > Key: YARN-5269 > URL: https://issues.apache.org/jira/browse/YARN-5269 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Affects Versions: YARN-2928 > Reporter: Joep Rottinghuis > Assignee: Haibo Chen > Labels: YARN-5355, yarn-5355-merge-blocker > > 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. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
