Yi Liang created HBASE-17861:
--------------------------------
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. See simulated permission section in
