Leemoonsoo commented on issue #3336: [ZEPPELIN-4078] Fix concurrent autocomplete and execute for Ipython URL: https://github.com/apache/zeppelin/pull/3336#issuecomment-474924351 Thanks @AyWa for the contribution. Looks like a test is failing with ``` 13:09:18,331 INFO org.apache.zeppelin.spark.OldSparkInterpreter:338 - ------ Create new SparkContext local ------- 13:09:18,335 INFO org.apache.spark.SparkContext:58 - Running Spark version 1.6.3 13:09:18,338 ERROR org.apache.spark.SparkContext:95 - Error initializing SparkContext. org.apache.spark.SparkException: An application name must be set in your configuration at org.apache.spark.SparkContext.<init>(SparkContext.scala:404) at org.apache.zeppelin.spark.OldSparkInterpreter.createSparkContext_1(OldSparkInterpreter.java:426) at org.apache.zeppelin.spark.OldSparkInterpreter.createSparkContext(OldSparkInterpreter.java:321) at org.apache.zeppelin.spark.OldSparkInterpreter.getSparkContext(OldSparkInterpreter.java:139) at org.apache.zeppelin.spark.OldSparkInterpreter.open(OldSparkInterpreter.java:696) at org.apache.zeppelin.spark.SparkInterpreter.open(SparkInterpreter.java:66) at org.apache.zeppelin.interpreter.LazyOpenInterpreter.open(LazyOpenInterpreter.java:69) at org.apache.zeppelin.interpreter.Interpreter.getInterpreterInTheSameSessionByClassName(Interpreter.java:354) at org.apache.zeppelin.interpreter.Interpreter.getInterpreterInTheSameSessionByClassName(Interpreter.java:365) at org.apache.zeppelin.spark.IPySparkInterpreter.open(IPySparkInterpreter.java:52) at org.apache.zeppelin.interpreter.LazyOpenInterpreter.open(LazyOpenInterpreter.java:69) at org.apache.zeppelin.spark.IPySparkInterpreterTest.startInterpreter(IPySparkInterpreterTest.java:93) at org.apache.zeppelin.python.IPythonInterpreterTest.testIpython_shouldNotHang_whenCallingAutoCompleteAndInterpretConcurrently(IPythonInterpreterTest.java:250) .... ``` Looks like https://github.com/apache/zeppelin/blob/master/spark/interpreter/src/test/java/org/apache/zeppelin/spark/IPySparkInterpreterTest.java#L59 is somehow not applied on the test.
