Please check if by any chance you have the "/etc/zeppelin/conf/interpreter.json" if it has correct read permission and also if the data inside this file is correct Or got corrupted by any chance.

- Also it will be good to try moving the "/usr/hdp/2.5.0.2-3/zeppelin/webapps/" directory to some other directory and then restart Zeppelin.

Example:

# mv  /usr/hdp/2.5.0.2-3/zeppelin/webapps   /Backup

.

Yes i have /etc/zeppelin/conf/interpreter.json Y and it has correct permission for read and data is no corrupted.

i move webapps directory in another and try to restart zeppelin. So it's not solve my problem.
