> Eliminate needless uses of FileSystem#{exists(), isFile(), isDirectory()}
> -------------------------------------------------------------------------
>
> Key: HADOOP-13427
> URL: https://issues.apache.org/jira/browse/HADOOP-13427
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs
> Affects Versions: 2.8.0
> Reporter: Steve Loughran
> Assignee: Steve Loughran
> Attachments: HADOOP-13427-001.patch, HADOOP-13427-002.patch,
> HADOOP-13427.003.patch
>
>
> We're cleaning up Hive and Spark's use of FileSystem.exists, because it is
> often the case we see code of exists+open, exists+delete, when the exists
> probe is needless. Against object stores, expensive needless.
> Hadoop can set an example here by stripping them out. It will also show where
> there are opportunities to optimise things better and/or improve reporting.
