I have a Pseudo-distributed cluster with Oozie 4.2.0, Hadoop 2.7, Hive 1.1.2 and Java 1.8. After I built the Oozie distribution with the components I am trying to copy the "shared lib" to HDFS. When I run the command it gives me the below error. I think a JAR file is missing (or it says so).
I am not a JAVA person and have no knowledge about this error what so ever. But, I think if I have built Oozie successfully with all required JAR files then this error should not crop up. I browsed through all other similar Oozie issues with JNI error but I found no credible answer to solve this issue. Can someone help me in this front here please?
oozie-setup.sh sharelib create -fs hdfs://localhost:9000
Error: A JNI error has occurred, please check your installation and try
again

I found the Solution for this myself,
Step 1 : Copy $HADOOP_INSTALL/share/common/*.jar to $OOZIE_INSTALL/libext
Step 2 : Rebuild the .WAR file.
Step 3 : Rerun oozie
