      Description

      Hi there 

      I am trying to optimize drill in mapr cluster, so it can perform as i think it should.

      I have this query : select * from dfs.`mypath` ORDER BY myindex DESC LIMIT 10;

      And it does not use the index, in the query plan.

      But as soon as i use a WHERE clause, the index is being used.

      Do some of you know, anything ?
