Not able to start any sessions from cloudera workbench

Hi,

 

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 ?

 

Thanks,

Hi 

 

 

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

Thanks,
Satz
