Jason Lowe reopened HADOOP-13500: --------------------------------- This is not a duplicate of HADOOP-13556. That JIRA only changed the getPropsWithPrefix method which was not involved in the error reported by this JIRA or TEZ-3413. AFAICT iterating a shared configuration object is still unsafe. > Concurrency issues when using Configuration iterator > ---------------------------------------------------- > > Key: HADOOP-13500 > URL: https://issues.apache.org/jira/browse/HADOOP-13500 > Project: Hadoop Common > Issue Type: Bug > Components: conf > Reporter: Jason Lowe > Assignee: Ajay Kumar > Priority: Major > > It is possible to encounter a ConcurrentModificationException while trying to > iterate a Configuration object. The iterator method tries to walk the > underlying Property object without proper synchronization, so another thread > simultaneously calling the set method can trigger it. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
