https://community.cloudera.com/t5/Support-Questions/spark-shell-master-yarn-error-in-HDP-2-6-5/m-p/281416#M209365 <P>Hi <a href="https://community.cloudera.com/t5/user/viewprofilepage/user-id/20288">@Shelton</a>&nbsp;</P><P>No specific steps actually. I just open HDP 2.6.5 Sandbox, connect it via ssh then run <STRONG>spark-shell --master yarn&nbsp;</STRONG></P><P>Alternatively, I tried to start Spark on Zeppelin and examined the logs. ERROR was the same.&nbsp;</P><P>Spark-shell has opened in local mode, no problem. But I can't start it yarn mode. But I managed to start a newly imported Sandbox.&nbsp;</P> Sun, 27 Oct 2019 12:23:01 GMT erkansirin78 2019-10-27T12:23:01Z
