Just hit the below NPE, I believe it was triggered by this query:

Thanks Joe. Can you list the contents of index directory on each of the
servers. In one of your earlier messages, you mentioned there were few
crashes. Did you clean up index directory before restarting?

If you haven't specified the data dir during start up, it should be under
/tmp/pinotServerData.

thanks,
Kishore G
