how to add columns to existing hive partitioned table?
<pre><code>alter table abc add columns (stats1 map&lt;string,string&gt;, stats2 map&lt;string,string&gt;)
</code></pre>

<p>i have altered my table with above query. But after while checking the data i got NULL's for the both extra columns. I'm not getting data.</p>
