Ahmet Altay reassigned BEAM-1801: --------------------------------- Assignee: Pablo Estrada (was: Ahmet Altay) > default_job_name can generate names not accepted by DataFlow > ------------------------------------------------------------ > > Key: BEAM-1801 > URL: https://issues.apache.org/jira/browse/BEAM-1801 > Project: Beam > Issue Type: Bug > Components: sdk-py > Reporter: Dennis Docter > Assignee: Pablo Estrada > Priority: Trivial > > The default job name generated by: > https://github.com/apache/beam/blob/master/sdks/python/apache_beam/runners/dataflow/internal/apiclient.py#L288 > is partially derived from the os username of the executing user. These may > contain characters not accepted by Dataflow, resulting in errors like: > apache_beam.runners.dataflow.dataflow_runner.DataflowRuntimeException: > Dataflow pipeline failed. State: FAILED, Error: > (a1b878f3562c0e6d): Error processing pipeline. Causes: (a1b878f3562c04ae): > Prefix for cluster 'beamapp-dennis.docter-032-03231324-1edc-harness' should > match '[a-z]([-a-z0-9]{0,61}[a-z0-9])?'. This probably means the joblabel is > invalid. > To solve this issue, sanitise the username to only container alphanumeric > characters and dashes. > Also there seems to be no length restriction and dataflow imposes a 63 > character length limit in the above case. Limiting on length substantially > shorter than that to allow for postfixes (like -harness in this case) may be > wise. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
