>                 URL: https://issues.apache.org/jira/browse/HADOOP-6499

>          Issue Type: Improvement
>            Reporter: Zheng Shao
>
> Currently most of the methods in Hadoop FileSystem has 2 ways of returning errors:
> 1. Return false
> 2. throw an IOException
> We should standardize what should happen in what case, so that the caller can retry/fail accordingly.
> The standard can be added to javadoc of FileSystem, then we need to verify all FileSystem implementation follow the same standard.
