      Description

      set hive.auto.convert.join=true;
      set hive.auto.convert.join.use.nonstaged=false;
      
      add jar hive-hcatalog-core.jar;
      
      drop table if exists t1;
      CREATE TABLE t1 (a string, b string)
      ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe';
      
      LOAD DATA LOCAL INPATH "data/files/sample.json" INTO TABLE t1;
      select * from t1 l join t1 r on l.a=r.a;
      

      The join will use a MapJoin which uses MapredLocalTask in a separate JVM to load the table into a Hashmap. But hive doesn't pass added jar to the classpath in such JVM so the following exception is thrown.
