Till Rohrmann closed FLINK-6174. -------------------------------- Resolution: Abandoned Issue has been abandoned. > Introduce a leader election service in yarn mode to make JobManager always > available > ------------------------------------------------------------------------------------ > > Key: FLINK-6174 > URL: https://issues.apache.org/jira/browse/FLINK-6174 > Project: Flink > Issue Type: Sub-task > Components: Runtime / Coordination > Reporter: Tao Wang > Assignee: Tao Wang > Priority: Major > Labels: pull-request-available > Time Spent: 10m > Remaining Estimate: 0h > > Now in yarn mode, if we use zookeeper as high availability choice, it will > create a election service to get a leader depending on zookeeper election. > When zookeeper leader crashes or the connection between JobManager and > zookeeper instance was broken, JobManager's leadership will be revoked and > send a Disconnect message to TaskManager, which will cancle all running tasks > and make them waiting connection rebuild between JM and ZK. > In yarn mode, we have one and only JobManager(AM) in same time, and it should > be alwasy leader instead of elected through zookeeper. We can introduce a new > leader election service in yarn mode to achive that. -- This message was sent by Atlassian Jira (v8.3.4#803005)
