Matei Zaharia updated HADOOP-5154: ---------------------------------- Attachment: hadoop-5154-v4.patch Updated patch to take into account your comments. I chose to call getRunningJobs before locking the scheduler (thus locking the JT alone, which is fine). It returns a new list so it should be okay to iterate through this list later. > 4-way deadlock in FairShare scheduler > ------------------------------------- > > Key: HADOOP-5154 > URL: https://issues.apache.org/jira/browse/HADOOP-5154 > Project: Hadoop Core > Issue Type: Bug > Components: contrib/fair-share > Reporter: Vinod K V > Assignee: Matei Zaharia > Priority: Blocker > Fix For: 0.18.4, 0.20.0 > > Attachments: FairSchedulerDeadLock.txt, hadoop-5154-v0.patch, > hadoop-5154-v1.patch, hadoop-5154-v2.patch, hadoop-5154-v3.patch, > hadoop-5154-v4.patch > > > This happened while trying to change the priority of a job from the scheduler > servlet. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
