How to filter array of key-values on a column in HBase?
<p>My Hbase table has a column which contains array of key-value pairs.</p>

<p>I read about <code>row-key</code>, <code>column family</code> or <code>column</code>, <code>custom filter</code> though,</p>

<p>I need scan columns which holding specific key name like...</p>

<pre><code>ROW1 , CF1, DATA_COLUMN : {KEY1:VALUE, KEY2:VALUE, KEY3:VALUE }
ROW2 , CF1, DATA_COLUMN : {KEY1:VALUE}
ROW3 , CF1, DATA_COLUMN : {KEY1:VALUE, KEY5:VALUE}
ROW4 , CF1, DATA_COLUMN : {KEY8:VALUE} &lt;--- Only needed row with KEY8 value set
</code></pre>

<p>I'm bushing around RDBMS wrapper but something more efficient way would exists, I think. Any advice would be appreciated.</p>
