Thanks for the suggestion Alex. However whenever I try anything beginning with file:/, file:// or file:/// or file://NNPRDHA/ I get this error:
org.springframework.web.client.RestClientException: Error running rest call; nested exception is org.springframework.web.client.HttpClientErrorException: 400 Bad Request It sounds like from what you’ve said it’s a Spark error rather than a Livy error, which I didn’t realise before. But whenever I put in a file argument value without a file: in front it - Livy or Spark? - assumes it’s an HDFS path and prepends it with hdfs://. Then Spark complains that only local Python files are supported. I’ve also tried copying the Python file from hdfs to the local file system of the Spark Master node. But I can’t specify that path in my POST call because if I use file: I get 400 Bad Request; and if I don’t use file: it (Spark?) assumes it’s in hdfs! Should I use the files argument for POST /batches too? Or the pyFiles argument, although I assumed that was for Python libraries required by the main application. I’ve tried lots of combinations but none have worked so far.

Have you tired passing the path in with file:// at the front (similar to hdfs://) that tells hdfs that the path is local, I've run into this issue with Spark before.

I’m invoking POST /batches from a Java REST client, passing in the path to the HDFS file as the ‘file’ argument of the POST request’s body (https://github.com/apache/incubator-livy/tree/branch-0.3#request-body-2<https://urldefense.proofpoint.com/v2/url?u=https-3A__github.com_apache_incubator-2Dlivy_tree_branch-2D0.3-23request-2Dbody-2D2&d=DwMFAg&c=jf_iaSHvJObTbx-siA1ZOg&r=S1_S7Dymu4ZL6g7L21O78VQZ53vEnAyZ-cx37DPYDyo&m=YIUsDYuvjVmUUxeP7zjxNhpuBW6QdaXW6qnaEbUiGf0&s=6Za80aGx9OBp6GXr8Ze8Di9eqsBXKDD4TraM-8HdumA&e=>). The value I’m providing for ‘file’ is "/user/MyUserName/hello.py". The POST response says the batch is in state ‘starting’ but when I query it using GET /batches/{batchId} I see this: Error: Only local python files are supported: hdfs://NNPRDHA/user/MyUserName/hello.py You can see the value has been altered from what I provided. How do I successfully invoke the Python file please?
