Zach York commented on HBASE-17861:
-----------------------------------

I'm not saying that you need to check every conceivable filesystem. I'm just 
saying perhaps the patch should exclude if the scheme contains s3 (which would 
cover s3, s3a, s3n, etc) rather than removing it for everything but hdfs (since 
there are likely other FS implementations other than hdfs that DO support rwx 
style permissions).

> Regionserver down when checking the permission of staging dir if 
> hbase.rootdir is on S3

> Found some issue, when set up HBASE-17437: Support specifying a WAL directory 
> outside of the root directory.
> The region server are  showdown when I add following config into 
> hbase-site.xml 
> hbase.rootdir = hdfs://xx/xx
> hbase.wal.dir = s3a://xx//xx
> hbase.coprocessor.region.classes = 
> org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint
> Error is below
> {noformat}
> org.apache.hadoop.hbase.security.access.SecureBulkLoadEndpoint threw 
> java.lang.IllegalStateException: Directory already exists but permissions 
> aren't set to '-rwx--x--x'
> {noformat}
> The reason is that, when hbase enable securebulkload, hbase will create a 
> folder in s3, it can not set above permission, because in s3, all files are 
> listed as having full read/write permissions and all directories appear to 
> have full rwx permissions. See Object stores have differerent authorization 
> models in 
> https://hadoop.apache.org/docs/current3/hadoop-aws/tools/hadoop-aws/index.html
