The Directory "/usr/lib/phoenix/" has the Phoenix Client & you mentioned the same Directory has Phoenix Server Jar as well. Kindly verify if the Permission on the JAR is Correct & confirm via "jar -tvf" on the Phoenix Server Jar that the Class "MetaDataEndpointImpl" is included in the same.    The Error indicates the Phoenix creating the SYSTEM Tables (Upon 1st Connection to Phoenix) is encountering the Error.

Additionally, Review the Master Logs to check for the Error Message at HBase Level as well.    - Smarak ... View more
