So far, we've configured the HA for Hadoop, so let's go through the page to see the Hadoop file system. 1. Analyze the status of active Namenode and standby namenode for client services. We can clearly see the directory structure of the Hadoop file system: Above all we are accessing Hadoop through active namenode, so if we can access Hadoop through standby namenode. Next we see that through standby namenode is inaccessible to Hadoop's file system. As prompted, we know that standby namenod
