<div id="body1589421645515"><p id="mrs_01_0759__p8060118">If you want to use a unified client API and a global namespace to access persistent storage systems including HDFS and OBS to separate computing from storage, you can configure the underlying storage system of Alluxio on MRS Manager. After a cluster is created, the default underlying storage address is <strong id="mrs_01_0759__b78361198822433">hdfs://hacluster/</strong>, that is, the HDFS root directory is mapped to Alluxio.</p>
