I have installed cloudera workbench with spark2, It was installed successfully but when I am trying to start a session it is getting stuck on 'Scala session (Base Image v2) starting...'
Could you please help if is there any workaround for this please ?

after intiating scala session ..go to terminal access cat /tmp/spark-driver.log
let me know error/exception you are facing.
please check your kerberos authentication for user configured in the cdsw
user-->settings-->Hadoop authentication-->check for kerbros ..If there is no ticket granted from kdc you wont get scala session.

Additionally, Could you please check if you are finding any suspicious log messages in "/var/log/cdsw/cdsw_health.log"
Also, could you please check if there is enough resources which you have requested for your session
