Review comment:
### 1. If interpreter process is normal, isRunning() must equal true
`isRunning()` is not a flag, It's a function call.
`interpreterProcess.isRunning()` Will call
`RemoteInterpreterUtils.java::checkIfRemoteEndpointAccessible()` , Check if the
remote interpreter is available through the socket.
### 2. Avoid invalid calls
`Job.abort()` Will go to the remote to call the interpreter,
`Interpreter.cancel(getInterpreterContext(null));` function. If the interpreter
is no longer connected, The `interpreter.cancel()` function cannot be called
correctly.
But if you find that the remote interpreter is not available in
`job.abort()`, Will pass again
`RemoteInterpreter.java::getOrCreateInterpreterProcess()`, Trying to create
an interpreter process, This will fail due to a 30 second timeout.
