      git.commit.id.abbrev=7b4c887

      I tried to call getObject on a column which is of type varchar, drill failed with the below error :

      Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/hadoop/io/Text
      	at org.apache.drill.exec.vector.VarCharVector$Accessor.getObject(VarCharVector.java:407)

      When the underlying type is a primitive, the getObject call succeeds
