             Summary: Regionserver down when checking the permission of staging dir if hbase.rootdir is on S3
                 Key: HBASE-17861
                 URL: https://issues.apache.org/jira/browse/HBASE-17861
             Project: HBase
          Issue Type: Bug
            Reporter: Yi Liang
            Assignee: Yi Liang


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.
