However there are bunch of improvements related to stability with these respective services. But that will not help in case the machine goes down.</P> Thu, 05 Jul 2018 18:56:51 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/HA-for-MapReduce2-History-server-Yarn-App-Timeline-Server/m-p/187231#M80315 sandyy006 2018-07-05T18:56:51Z https://community.cloudera.com/t5/Archives-of-Support-Questions/HA-for-MapReduce2-History-server-Yarn-App-Timeline-Server/m-p/187232#M80316 <P><A rel="user" href="https://community.cloudera.com/users/81162/sameermrinal.html" nodeid="81162">@Sameer Mrinal</A> If you found this answer addressed your question, please take a moment to login and click the "accept" link on the answer. <span class="lia-unicode-emoji" title=":slightly_smiling_face:">🙂</span> </P> Fri, 06 Jul 2018 15:30:21 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/HA-for-MapReduce2-History-server-Yarn-App-Timeline-Server/m-p/187232#M80316 sandyy006 2018-07-06T15:30:21Z
