It is either down or not responding on 8032 on time. </P> Tue, 31 May 2016 02:13:02 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Exception-while-invoking-getNewApplication-of-class/m-p/109020#M30133 ravi1 2016-05-31T02:13:02Z https://community.cloudera.com/t5/Archives-of-Support-Questions/Exception-while-invoking-getNewApplication-of-class/m-p/109021#M30134 <P>Thank you Ravi.</P><P> HA Zookeeper Connection State: Auto Failover is not enabled, after enabling this it worked.</P> Tue, 31 May 2016 20:39:51 GMT https://community.cloudera.com/t5/Archives-of-Support-Questions/Exception-while-invoking-getNewApplication-of-class/m-p/109021#M30134 Neyyu 2016-05-31T20:39:51Z
