Description

Behavior:

Changes are made to conf/interpreter.json under the Spark group:

• interpreterGroup -> spark -> defaultInterpreter => set value to "false"
• interpreterGroup -> pyspark -> defaultInterpreter => set value to "true"
• moved the pyspark entry above spark entry

As shown below

"2CC2YSMHR": {
      "id": "2CC2YSMHR",
      "name": "spark",
      "group": "spark",
      "properties": {
        "spark.executor.memory": "",
        "args": "",
        ...
        "zeppelin.R.cmd": "R"
      },
      "status": "READY",
      "interpreterGroup": [
        {
          "name": "pyspark",
          "class": "org.apache.zeppelin.spark.PySparkInterpreter",
          "defaultInterpreter": true,
          "editor": {
            "language": "python"
          }
        },
        {
          "name": "spark",
          "class": "org.apache.zeppelin.spark.SparkInterpreter",
          "defaultInterpreter": false,
          "editor": {
            "language": "scala"
          }
        },
        ...

However, In the web UI -> Settings -> Interpreter binding page:

The first list item becomes:

spark %spark (default) , %spark , %sql , %dep , %r

Notice that the text in red actually should be "pyspark", which is missing now

The default interpreter is successfully set to PySpark though
