Ji Liu commented on FLINK-9542:
-------------------------------
[~Zentol] Is this issue still open? I quickly looked into the code and it seems
that _DistributedCacheEntries_ still keeps String as file-path. I would like to
provide a fix.
> ExEnv#registerCachedFile should accept Path

> Key: FLINK-9542
> URL: https://issues.apache.org/jira/browse/FLINK-9542
> Project: Flink
> Issue Type: Improvement
> Components: API / DataSet, API / DataStream
> Reporter: Chesnay Schepler
> Priority: Major
>
> Currently, {{registerCachedFile}} accepts {{Strings}} as file-paths.
> This is undesirable because invalid paths are detected much later than
> necessary; at the moment this happens when we attempt to upload them to the
> blob store, i.e. during job submission, when ideally it should fail right
> away.
> As an intermediate solution we can modify the {{DistributedCacheEntries}} to
> contain {{Paths}} instead of {{Strings}}. This will not require API changes
> but still allow earlier detection.
