java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient

Question

I have Hadoop 2.7.1 and apache-hive-1.2.1 versions installed on ubuntu 14.0.

1. Why this error is occurring ?
2. Is any metastore installation required?

Answer 1

This is probably due to its lack of connections to the Hive Meta Store,my hive Meta Store is stored in Mysql,so I need to visit Mysql,So I add a dependency in my build.sbt

libraryDependencies += "mysql" % "mysql-connector-java" % "5.1.38"

and the problem is solved!
