Mingliang Qi commented on FLINK-805:
------------------------------------
I think for distributed filesystem it is checked at job start. For local
filesystem we didn't check it on master node, is it because sometimes the file
are not shared among cluster nodes?
> Early check of output write permissions

> Key: FLINK-805
> URL: https://issues.apache.org/jira/browse/FLINK-805
> Project: Flink
> Issue Type: Improvement
> Reporter: GitHub Import
> Labels: github-import
> Fix For: pre-apache
>
>
> FileDataSinks start to write output data once the first tuple arrives.
> If a DataSink follows a non-pipelined expensive data flow, the sink might
> fail due to missing write permissions after a significant portion of the data
> flow has been processed.
> It would be good to check the write permissions early (before or at job
> start) and to immediately cause the job to fail in case of missing write
> permissions.
