A user received the follow error when starting Looker on a cluster with the command
./looker start :
"<script> start requires at least 0 argument: "<script> start"."
We found that the startup flag for --clustered needs to have no value instead "Yes". For example, specify
LOOKERARGS="--clustered -d looker-db" to specify to start in clustered mode and use the MySQL backend database specified in the looker-db file.
