Configuring HBase Configure HBase to use Kerberos HBase supports Kerberos security only, and can run securely independently of the security status of your MapR cluster. Configure HBase ACLs HBase supports Access Control Lists (ACLs) to limit the privileges of users on the system. Before you can use ACLs, you need to perform the steps to enable ACLs. Set Up Compression with HBase Using compression with HBase reduces the number of bytes transmitted over the network and stored on disk. These benefits often outweigh the performance cost of compressing the data on every write and uncompressing it on every read. Set up LZO Compression for HBase Configure the Default Database for HBase Clients For Hbase version 1.1 and above, a default database configuration determines whether clients connect to HBase tables or MapR-DB tables. You can change the default setting for all Hbase clients or you can set the database for a particular job. This setting is ignored for HBase 0.98.12 client connections.
