I am trying to run oozie within a docker that also has Hadoop 2.6.0 installed and started. I used the instructions mentioned, but still facing the same problem for both oozie 5.2.0 and 5.1.0. I tried changing Hadoop versions as well but still not no solution. The error I am facing on when running the using oozied.sh: 
{code:java}
Error: A JNI error has occurred, please check your installation and try again
