I tried to install Apache oozie in EMR cluster. I am getting the error. “Error: IO_ERROR : java.net.ConnectException: Connection refused”.
Followed the below link for installation: http://pkavuri.blogspot.in/2013/08/oozie-installation-is-simplified.html
I got the error after running the below command:
bin/oozie admin -oozie http://localhost:11000/oozie -status
The following steps I did after encountering the error:
Moved the Hadoop and common jar files to the folders “/oozie-3.3.2/distro/target/oozie-3.3.2-distro/oozie-3.3.2/oozie-server/webapps/oozie/WEB-INF/lib” and “oozie-3.3.2/distro/target/oozie-3.3.2-distro/oozie-3.3.2/lib/”
Downloaded derby in oozie-3.3.2/libext
The error trace after running the command "tail -100f logs/catalina.out":
