Summary: S3GuardTool to support FilterFileSystem
Key: HADOOP-16722
URL: https://issues.apache.org/jira/browse/HADOOP-16722
Project: Hadoop Common
Issue Type: Improvement
Components: fs/s3
Reporter: Mingliang Liu
Currently S3GuardTool is operating against a S3AFileSystem implementation.
There are cases where the {{fs.hboss.fs.s3a.impl}} is a FilterFileSystem
wrapping another implementation. For example, [[HBASE-23314]] made
{{HBaseObjectStoreSemantics}} a {{FilterFileSystem}} from {{FileSystem}}.
S3GuardTool could use {{FilterFileSystem::getRawFileSystem}} method to get the
wrapped S3AFileSystem implementation. Without this support, a simple
S3GuardTool against HBOSS will get confusing error like "s3a://mybucket is not
a S3A file system".
