Steve Loughran commented on HADOOP-15000:
-----------------------------------------
Its deprecated more at the caller level, than the implementor. We, FS
implementors, always have to implement it.
Why don't we want callers to use it? Because with aggregate filesystems
(viewfs) the blocksize may vary depending on which bit of the path you are
looking at. Same for different storage layers, where SSD may have a different
policy from HDD.
> s3a new getdefaultblocksize be called in getFileStatus which has not been
> implemented in s3afilesystem yet

> new implementation of getting block size has been called in getFileStatus
> method:
> {code:java}
> return new S3AFileStatus(meta.getContentLength(),
> dateToLong(meta.getLastModified()),
> path,
> getDefaultBlockSize(path),
> username);
> }
