(usually less than 30 seconds) after HBase is started for its initializatio

Apache PredictionIO can be done through the <code>pio</code> command. Please 
add PIO binary command path to to your <code>PATH</code> first. Assuming

Modeling</h1></div></div><div class="content"> <p>This section explains how to 
model your app
 lication data as events.</p><p><strong>Entity</strong>: it&#39;s the real 
world object involved in the events. The entity may perform the events, or 
interact with other entity (which became <code>targetEntity</code> in an 
event).</p><p>For example, your application may have users and some items which 
the user can interact with. Then you can model them as two entity types: 
<strong>user</strong> and <strong>item</strong> and the entityId can uniquely 
identify the entity within each entityType (e.g. user with ID 1, item with ID 
1).</p><p>An entity may perform some events (e.g user 1 does something), and 
entity may have properties associated with it (e.g. user may have gender, age, 
email etc). Hence, <strong>events</strong> involve <strong>entities</strong> 
and there are three types of events, respectively:</p> <ol> <li>Generic events 
performed by an entity.</li> <li>Special events for recording changes of an 
entity&#39;s properties</li> <li>Batch events</li> </ol> <p>They are explained
  in details below.</p><h2 id='1.-generic-events-performed-by-an-entity' 
class='header-anchors'>1. Generic events performed by an entity</h2><p>Whenever 
the entity performs an action, you can describe such event as <code>entity 
&quot;verb&quot; targetEntity with &quot;some extra information&quot;</code>. 
The <em>&quot;targetEntity&quot;</em> and <em>&quot;some extra 
information&quot;</em> can be optional. The <em>&quot;verb&quot;</em> can be 
used as the name of the <em>&quot;event&quot;</em>. The <em>&quot;some extra 
information&quot;</em> can be recorded as <code>properties</code> of the 
event.</p><p>The following are some simple examples:</p> <ul> <li>user-1 
signs-up</li> </ul> <div class="highlight json"><table style="border-spacing:
