Issue with SparkSqlInterpreter

Hi,

I am having an issue with %sql interpreter in Zeppelin. I am running Zeppelin 0.5.6.
Each time a query is made in %sql (SparkSqlInterpreter), the interpreter needs to be restarted for the next query to work.
If we try to run two select queries in two paragraphs using %sql interpreter one after the other Zeppelin throws the following error for the second query (both in HiveContext mode and in Spark SQLContext mode) –

org.apache.spark.sql.AnalysisException: Conf non-local session path expected to be non-null; at org.apache.spark.sql.hive.HiveQl$.createPlan(HiveQl.scala:260) at org.apache.spark.sql.hive.ExtendedHiveQlParser$$anonfun$hiveQl$1.apply(ExtendedHiveQlParser.scala:41) at org.apache.spark.sql.hive.ExtendedHiveQlParser$$anonfun$hiveQl$1.apply(ExtendedHiveQlParser.scala:40) at scala.util.parsing.combinator.Parsers$Success.map(Parsers.scala:136) at scala.util.parsing.combinator.Parsers$Success.map(Parsers.scala:135)

Is this an existing issue? Can you suggest some solution?
