+ == 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.
