MySQL is required for swarming. By default, NuPIC expects you to have a root
user with no password. If you are uncomfortable with that, you’ll need to update the default NuPIC configuration file at $NUPIC/config/default/nupic-default.xml
. The markup to update is:
<property>
<name>nupic.cluster.database.user</name>
<value>root</value>
<description>Username for the MySQL database server </description>
</property>
<property>
<name>nupic.cluster.database.passwd</name>
<value></value>
<description>Password for the MySQL database server </description>
</property>
