Weizhong commented on CARBONDATA-1030:
--------------------------------------

We can add mapreduce.input.carboninputformat.segmentnumbers on mapred-site.xml, 
so that we can query from specified segments
{noformat}
<property>
  <name>mapreduce.input.carboninputformat.segmentnumbers</name>
  <value>0,1</value>
</property>
{noformat}

> Support reading specified segment or carbondata file

> We can query whole table in SQL way currently, but reading specified segments 
> or data files is useful in some scenarios such as incremental data processing.
