Command to get HBase table owner

Is there any command to get complete description about hbase table such as owner, database, modified time, etc.

In hive, i can get those information using

desc formatted tablename

But in hbase desc 'tablename' shows size, version, replication_scope, etc.

I want to get owner details of hbase table.

Thanks.

First, add access control related config to hbase-site.xml :

   <property>
      <name>hbase.security.authorization</name>
      <value>true</value>
   </property>
   <property>
      <name>hbase.coprocessor.master.classes</name>
      <value>org.apache.hadoop.hbase.security.access.AccessController</value>
   </property>
   <property>
      <name>hbase.coprocessor.region.classes</name>
      <value>org.apache.hadoop.hbase.security.token.TokenProvider,org.apache.hadoop.hbase.security.access.AccessController</value>
   </property>

You can follow the instructions here, maybe have to restart hbase after the modification.

Then, set the owner of one table, and describe it 

hbase(main):007:0> alter 'MyTable', {OWNER => 'sel-fish'}
Updating all regions with the new schema...
1/1 regions updated.
Done.

hbase(main):008:0> desc 'MyTable'
Table MyTable is ENABLED
MyTable, {TABLE_ATTRIBUTES => {METADATA => {'OWNER' => 'sel-fish'}}
COLUMN FAMILIES DESCRIPTION
{NAME => 'cf', DATA_BLOCK_ENCODING => 'NONE', BLOOMFILTER => 'ROW', REPLICATION_SCOPE => '0', COMPRESSION => 'NONE', VERSIONS => '2147483647', TTL => '500 SECONDS (8 MINUTES 20 SECO
NDS)', MIN_VERSIONS => '0', KEEP_DELETED_CELLS => 'FALSE', BLOCKSIZE => '65536', IN_MEMORY => 'false', BLOCKCACHE => 'true'}
1 row(s) in 0.0300 seconds
