https://community.cloudera.com/t5/Support-Questions/NoSuchMethodError-for-org-apache-hadoop-ipc-RemoteException/m-p/220494#M182379 <P>This is likely because log4j-1.2.x.jar is in your classpath somewhere which is getting bundled up in LLAP package. Hive2 and LLAP moved to log4-2.x which is not compatible with old log4j.. If you have HADOOP_USER_CLASSPATH_FIRST set to true in your environment, old log4j should not be picked. It could also be that hive libs directory is transitively pulling old log4j.</P><P>When LLAP bundles a package only the following log4j 2.x jars are expected</P><P>log4j-1.2-api-2.8.2.jar (bridge jar)</P><P>log4j-api-2.8.2.jar</P><P>log4j-core-2.8.2.jar</P><P>log4j-jul-2.5.jar</P><P>log4j-slf4j-impl-2.8.2.jar</P><P>log4j-web-2.8.2.jar</P><P>Can you check if your hadoop classpath is having log4j-1.2.x.jar by any chance? If so please back that up somewhere/remove and retry.</P> Sat, 09 Dec 2017 04:04:54 GMT pjayachandran 2017-12-09T04:04:54Z
