Date Sat, 10 Sep 2011 05:01:18 GMT

Comment:
minor fix

   * List more than one name node directory in the configuration, so that multiple copies
of the file system meta-data will be stored. As long as the directories are on separate disks,
a single disk failure will not corrupt the meta-data.
   * Configure the NameNode to store one set of transaction logs on a separate disk from the
image.
   * Configure the NameNode to store another set of transaction logs to a network mounted
disk.
-  * Monitor the disk space available to the NameNode. If is getting low, add more storage.
+  * Monitor the disk space available to the NameNode. If free space is getting low, add more
storage.
   * Do not host DataNode, JobTracker or TaskTracker services on the same system.
  
  If a NameNode does not start up, look at the TroubleShooting page.
