@akshay singh check if kafka process is running with these parameters

-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false

see a similar issue when jmx is not bound to port in HDP distribution so you need to set JMX_PORT env variable and restart kafka process
