Getting 103 error when trying to connect to phoenix from a spring boot project in a kerberized cluster.

Explorer

I am including phoenix, hbase and zookeeper jars in the project. I have placed the configuration xml files (hbase-site.xml, core-site.xml and hdfs-site.xml) in the src directory(also tried src/main/resources) where all the java files are. This worked for me in a simple java project, but i am unable to make it hit the config files in a spring boot project. Can anyone help?

I got this fixed. Had to add a dependency for netty-all in the pom file.
