Summary: Enhance hbase services autorestart capability to hbase-daemon.sh Key: HBASE-15924 URL: https://issues.apache.org/jira/browse/HBASE-15924 Project: HBase Issue Type: Improvement Affects Versions: 0.98.19 Reporter: Loknath Priyatham Teja Singamsetty Fix For: 0.98.19 As part of HBASE-5939, the autorestart of hbase services has been added to deal with scenarios where hbase services (master/regionserver/master-backup) gets killed or goes down leading to unplanned outages. The changes were made to hbase-daemon.sh with the help of autorestart option. However, the autorestart implementation doesn't work in standalone mode and have few gaps with the implementation as per release notes of HBASE-5939. Here is an attempt to re-design and fix the functionality considered all possible usecases with hbase service operations. Release Notes of HBASE-5939: ------------------------------------------ When launched with autorestart, HBase processes will automatically restart if they are not properly terminated, either by a "stop" command or by a cluster stop. To ensure that it does not overload the system when the server itself is corrupted and the process cannot be restarted, the server sleeps for 5 minutes before restarting if it was already started 5 minutes ago previously. To use it, launch the process with "bin/start-hbase autorestart". This option is not fully compatible with the existing "restart" command: if you ask for a restart on a server launched with autorestart, the server will restart but the next server instance won't be automatically restarted. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
