{code}
but on re-saving it works fine.
Steps to reproduce:
Configure following as dependencies in JDBC 
{code}
org.apache.hive:hive-jdbc:2.0.1	
org.apache.hadoop:hadoop-common:2.7.1	
org.apache.hive.shims:hive-shims-0.23:2.1.0	
org.apache.phoenix:phoenix-core:4.7.0-HBase-1.1
{code}
now try changing one of it, say "org.apache.hadoop:hadoop-common:2.7.1" to "org.apache.hadoop:hadoop-common:2.6.0"
