Chesnay Schepler commented on FLINK-8114: ----------------------------------------- The argument forwarding is pretty much completely broken. It only works for exactly 1 argument. 0 arguments result in an empty string being passed as an argument, multiple arguments are passed in as a single argument. > NO-arg scripts are given an empty string as argument > ---------------------------------------------------- > > Key: FLINK-8114 > URL: https://issues.apache.org/jira/browse/FLINK-8114 > Project: Flink > Issue Type: Bug > Components: Python API > Affects Versions: 1.4.0 > Reporter: Chesnay Schepler > Assignee: Chesnay Schepler > Fix For: 1.4.0 > > > Each PythonStreamer instance passes the original program arguments to the > python process upon creation. However, not check is made whether there were > any arguments at all, which results in an empty String being passed as an > argument. > {code} > process = Runtime.getRuntime().exec(new String[] {pythonBinaryPath, "-O", > "-B", planPath, arguments}); > {code} -- This message was sent by Atlassian JIRA (v6.4.14#64029)
