+ == Problem: Created Root Directory for HBase through Hadoop DFS ==
+  * On Startup, Master says that you need to run the hbase migrations script. 
Upon running that, the hbase migrations script says no files in root directory.
+ === Causes ===
+  * HBase expects the root directory to either not exist, or to have already 
been initialized by hbase running a previous time. If you create a new 
directory for HBase using Hadoop DFS, this error will occur.
+ === Resolution ===
+  * Make sure the HBase root directory does not currently exist or has been 
initialized by a previous run of HBase. Sure fire solution is to just use 
Hadoop dfs to delete the HBase root and let HBase create and initialize the 
directory itself.
