+ * S3ObjectStorageClassFilter will filter the S3 files based on the
fs.s3a.glacier.read.restored.objects configuration set in S3AFileSystem
+ * The config can have 3 values:
+ * READ_ALL: This would conform to the current default behavior of not taking
into account the storage classes retrieved from S3. This will be done to keep
the current behavior for the customers and not changing the experience for them.
+ * SKIP_ALL_GLACIER: If this value is set then this will ignore any S3 Objects
which are tagged with Glacier storage classes and retrieve the others.
+ * READ_RESTORED_GLACIER_OBJECTS: If this value is set then restored status of
the Glacier object will be checked, if restored the objects would be read like
normal S3 objects else they will be ignored as the objects would not have been
retrieved from the S3 Glacier.

Review Comment:
GLACIER_IR files, are instantly available so no failure is observed. S3A
will be able to access the same.

> Handle S3A "glacier" data

> Key: HADOOP-14837
> URL: https://issues.apache.org/jira/browse/HADOOP-14837
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.0.0-beta1
> Reporter: Steve Loughran
> Priority: Minor
> Labels: pull-request-available
>
> SPARK-21797 covers how if you have AWS S3 set to copy some files to glacier,
> they appear in the listing but GETs fail, and so does everything else
> We should think about how best to handle this.
> # report better
> # if listings can identify files which are glaciated then maybe we could have
> an option to filter them out
> # test & see what happens
