> Project: HBase
> Issue Type: Sub-task
> Reporter: Yi Mei
> Assignee: Yi Mei
> Priority: Major
> Fix For: 3.0.0, 2.3.0
>
>
> When create table, table directories are firstly created in tmp directory and
> then move to data directory. So HDFS ACLs are set at the following tmp
> directories used for ACLs inherited:
> {code:java}
> {hbase-rootdir}/.tmp/data
> {hbase-rootdir}/.tmp/data/{namespace}
> {hbase-rootdir}/.tmp/data/{namespace}/{table}
> {code}
> When master restart, it will delete tmp directory and this will break this
> feature.
