Hello,

so I'm trying to get hbase installed.

I've followed the instructions on the quick-tutorial and I can startup hbase
but when I actually try to create a table I get an error.

Looking at the log file here's the output:

Are you trying to install HBase in a standalone mode? Can you give
some more details like what your local system looks like (cygwin / Mac
/ Linux etc)

Try the following things:
1) Start hbase and use the master web ui
(http://localhost:60010/master.jsp) to ensure that *all* hostnames are
reflected as localhost.

2) If you see any IP addresses that are not 127.0.0.1, you would need
to use the hbase.(zookeeper|master|regionserver).dns.interface
configuration to bind it to localhost. See
http://opentsdb.net/setup-hbase.html for an example configuration file
with these fields. The exact value would change based on your system
(cygwin/Mac/Linux etc)

3) Look at the master log (under $HBASE_HOME/logs) to see if there are
any errors / stack traces that could point you to more information.

4) Lastly, try deleting your /hbase directory before a clean start in
case you have been having installation issues for a while (to make
sure that you are starting with a clean slate)

Use a service like pastebin.com to post logs as email mangles it up.

I figured out my problem.

The docs specifically say to specify the location of the db date via
file:///your/path/here and instead I simply decided to make it
/your/path/here

Once I used the file:/// convention everything went smooth.

Thanks for the help.
