Hi, I've installed Zeppelin 7.3 and tried to run Zeppelin Tutorial/Basic Features (Spark). However, there was an error when I ran it as follows:
paragraph_1423500779206_-1502780787's Interpreter null not found org.apache.zeppelin.interpreter.InterpreterException: paragraph_1423500779206_-1502780787's Interpreter null not found at org.apache.zeppelin.notebook.Note.run(Note.java:621) at org.apache.zeppelin.socket.NotebookServer.persistAndExecuteSingleParagraph(NotebookServer.java:1647) at org.apache.zeppelin.socket.NotebookServer.runParagraph(NotebookServer.java:1621) at org.apache.zeppelin.socket.NotebookServer.onMessage(NotebookServer.java:266) at org.apache.zeppelin.socket.NotebookSocket.onWebSocketText(NotebookSocket.java:59) at org.eclipse.jetty.websocket.common.events.JettyListenerEventDriver.onTextMessage(JettyListenerEventDriver.java:128) at org.eclipse.jetty.websocket.common.message.SimpleTextMessage.messageComplete(SimpleTextMessage.java:69) at org.eclipse.jetty.websocket.common.events.AbstractEventDriver.appendMessage(AbstractEventDriver.java:65) at org.eclipse.jetty.websocket.common.events.JettyListenerEventDriver.onTextFrame(JettyListenerEventDriver.java:122) at org.eclipse.jetty.websocket.common.events.AbstractEventDriver.incomingFrame(AbstractEventDriver.java:161) at org.eclipse.jetty.websocket.common.WebSocketSession.incomingFrame(WebSocketSession.java:309) at org.eclipse.jetty.websocket.common.extensions.ExtensionStack.incomingFrame(ExtensionStack.java:214) at org.eclipse.jetty.websocket.common.Parser.notifyFrame(Parser.java:220) at org.eclipse.jetty.websocket.common.Parser.parse(Parser.java:258) at org.eclipse.jetty.websocket.common.io.AbstractWebSocketConnection.readParse(AbstractWebSocketConnection.java:632) at org.eclipse.jetty.websocket.common.io.AbstractWebSocketConnection.onFillable(AbstractWebSocketConnection.java:480) at org.eclipse.jetty.io.AbstractConnection$2.run(AbstractConnection.java:544) at org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:635) at org.eclipse.jetty.util.thread.QueuedThreadPool$3.run(QueuedThreadPool.java:555) at java.lang.Thread.run(Thread.java:748) So, I created a new notebook, copied code from the sample notebook and ran. Then, it worked. Is there any way to avoid the error shown above ? Thanks MH
