Varun Saxena commented on YARN-5109: ------------------------------------ Yes I have taken that patch and working on top of it. > timestamps are stored unencoded causing parse errors > ---------------------------------------------------- > > Key: YARN-5109 > URL: https://issues.apache.org/jira/browse/YARN-5109 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Affects Versions: YARN-2928 > Reporter: Sangjin Lee > Assignee: Varun Saxena > Priority: Blocker > Labels: yarn-2928-1st-milestone > Attachments: YARN-5109-YARN-2928.01.patch, > YARN-5109-YARN-2928.02.patch > > > When we store timestamps (for example as part of the row key or part of the > column name for an event), the bytes are used as is without any encoding. If > the byte value happens to contain a separator character we use (e.g. "!" or > "="), it causes a parse failure when we read it. > I came across this while looking into this error in the timeline reader: > {noformat} > 2016-05-17 21:28:38,643 WARN > org.apache.hadoop.yarn.server.timelineservice.storage.common.TimelineStorageUtils: > incorrectly formatted column name: it will be discarded > {noformat} > I traced the data that was causing this, and the column name (for the event) > was the following: > {noformat} > i:e!YARN_RM_CONTAINER_CREATED=\x7F\xFF\xFE\xABDY=\x99=YARN_CONTAINER_ALLOCATED_HOST > {noformat} > Note that the column name is supposed to be of the format (event > id)=(timestamp)=(event info key). However, observe the timestamp portion: > {noformat} > \x7F\xFF\xFE\xABDY=\x99 > {noformat} > The presence of the separator ("=") causes the parse error. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
