| teragrep exec hdfs load filename returns NPE with "empty" avro files #268

Describe the bug I tried to load a saved avro file to see its contents and got following:

java.lang.NullPointerException at org.apache.zeppelin.interpreter.InterpreterOutput.write(InterpreterOutput.java:334) at org.apache.zeppelin.interpreter.InterpreterResult.add(InterpreterResult.java:90) at org.apache.zeppelin.interpreter.InterpreterResult.(InterpreterResult.java:75) at com.teragrep.pth_07.DPLExecutor.interpret(DPLExecutor.java:209) ...

Expected behavior Query should produce 0 results.

How to reproduce Save empty result set as avro, files contain headers only.
