Taewoo Kim closed ASTERIXDB-1924.
---------------------------------
Resolution: Invalid
This happens when you use the Ansible script - start.sh to start your instance
and send the query right after the script. As [~buyingyi] confirmed, what
Ansible does is starting CCDriver and NCDriver. So, we need to wait about 10
seconds to let the cluster change its status to be ACTIVE.
