@KC could you please follow this tutorial http://www.mkyong.com/maven/create-a-fat-jar-file-maven-shade-plugin/

this jar is used by the zeppelin server at runtime zeppelin/lib/interpreter/spark/dep/zeppelin-spark-dependencies-0.6.0.2.4.0.0-169.jar, will be good if you have your version of jar shaded.

Are you using HiveInputFormat, its better to use CombineInputFormat which combine all small files to generate a split.

@KCcan you lookout for these two jars, i m suspecting that zepplien spark dependency is causing this issue. zeppelin/lib/interpreter/spark/dep/zeppelin-spark-dependencies-0.6.0.2.4.0.0-169.jar /zeppelin/lib/interpreter/flink/jackson-databind-2.4.2.jar

please look into zeepline lib folder.

seems you have library mismatch for jackson, could you please verify which jars contain this class com.fasterxml.jackson.databind.node.ArrayNode,isolate those jars and maintain a single version of jars available across the classpath. if you still want to use to different jar version then please consider jar shading.

after df=hive_context.sql("SELECT blglast FROM tab_temp AS b limit 50"), you can get the row object in which you can perform your custom logic. >>> for row in df.rdd.collect(): ... dosomething ...

what is your sample data here, table DDL?

@Manikandan Durairaj you can take the advantage of regular expression with getFile, something like this https://community.hortonworks.com/questions/38120/how-to-get-files-based-on-the-time-stamp-in-nifi.html

@Vijay Parmar you are getting this error from bash shell, you can not run the query from bash shell.use hive cli to run this query.
