Dear community,
Trying to deploy a cluster via blueprint, but obtain a wierd error:
ERROR [ambari-client-thread-24] QueryParser:115 - Lowercase host_name value in expression failed with error:java.lang.NullPointerException
Had not found this error anywhere in documentation so trying to ask here.

Seems the problem was with nodes specified in cluster configuration. They were not correctly provisioned. However the error looks wierd.

double check the values you entered in the host_name field, do you have a space there maybe?
This is what it suppose to look like, for anything else paste your blueprint
"blueprint" : "multi-node-hdfs-yarn", "host_group" : "slaves", "host_name" : "c6404.ambari.apache.org"

Can you attach your blueprint json file?
