Fengdong Yu created HDFS-4631: --------------------------------- Summary: Support customized call back method during failover automatically. Key: HDFS-4631 URL: https://issues.apache.org/jira/browse/HDFS-4631 Project: Hadoop HDFS Issue Type: Improvement Components: ha Affects Versions: 3.0.0 Reporter: Fengdong Yu Fix For: 3.0.0 ZKFC add HealthCallbacks bu default, this can do quiteElection at least. but we often want to be alerted if there is fail over occurring(such as send email, short message), especially for prod cluster. There is a configured fence script. maybe we can put all these logics in the script. but in reasonable, fence script does only one thing: fence :) So I added this patch, we can configure customized HM callback method, if there is no configration, then only HealthCallbacks is added. -- This message is automatically generated by JIRA.
