Description

since the service names are same and they both referring to same location for pid files, we can not start both services at once.

Tweak is to export HADOOP_PID_DIR to different location after starting one service and start other one.

It would be better to have different pid file names.

 

 

Umas-MacBook-Pro ozone-0.5.0-beta % bin/ozone --daemon start datanode
datanode is running as process 25167.  Stop it first.
