   1. Move the download to wherever you want to run hbase from, say to {{{~/hbase}}}
   1. If running a remote HDFS that you want hbase to connnect to, edit {{{conf/hbase-site.xml}}} and add a property for {{{hbase.rootdir}}}.  Set it to {{{hdfs://NAMENODE_HOST:NAMENODE_PORT/HBASE_ROOTDIR}}}.  For example, {{{hdfs://localhost:9000/hbase}}}.  Otherwise, use the default: {{{file:///tmp/hbase-${user.home}/hbase}}} UNLESS you are running on windows (TODO: Restore what you do here when on windows -- St.Ack).
   1. Edit {{{conf/hbase-env.sh}}} and define {{{JAVA_HOME}}}
+  1. Make sure that you can log into {{{localhost}}} without a password (see [http://hadoop.apache.org/core/docs/current/quickstart.html Hadoop Quick Start], "Setup passphraseless ssh"). ''Test this out first!'' New versions of ssh require accepting a new foreign host key ''before'' logging in, even if the host is configured with authorized keys.
   1. Start hbase with ~/hbase/bin/start-hbase.sh (hbase logs are viewable in ~/hbase/logs by default)
   1. Enter hbase shell by running ~/hbase/bin/hbase shell; type 'help<ENTER>' to see shell help
   1. Have fun with hbase
