Enterprise-class big data clusters must meet the following requirements:</p>

<ul id="admin_guide_000089__u4968d14afd2d4caf99d9f292c69692af"><li id="admin_guide_000089__l1482155c5cff41b7a30382a53fa41ed0">Carry data of different types and formats and run jobs and applications of different types (such analysis, query, and stream processing).</li><li id="admin_guide_000089__lcd353ff1c67d4afdb4702c48c8fbec88">Isolate data of a user from that of another user who has demanding requirements on data security, such as a bank or government institute.</li></ul>

<p id="admin_guide_000089__a937b0524d44642a1b355cc5bcec8f795">The preceding requirements bring the following challenges to the big data clusters:</p>

<p id="admin_guide_000089__a9940f938b79742fe9d142148c86b8f9e">Multi-tenancy isolates the resources of a big data cluster into resource sets. Users can lease desired resource sets to run applications and jobs and store data. In a big data cluster, multiple resource sets can be deployed to meet diverse requirements of multiple users.</p>
