             Summary: IndexOutOfBoundsException for pruning on date column (at 
large scale)
                 Key: DRILL-3947
                 URL: https://issues.apache.org/jira/browse/DRILL-3947
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.2.0
            Reporter: Aman Sinha
            Assignee: Aman Sinha


When a large table (about 52 B records, 10K files, created with CTAS 
auto-partitioning) partitioned by a 'date' column,  partition pruning is 
encountering an error.  At smaller scales, partition pruning succeeds. At this 
time, the problem seems specific to date columns only. This column is a 
nullable column and has NULL values in the data. 

Here's the query:
{code}
explain plan for select count(*) from `table` where `date` = '2015-07-01';
{code}

Here's the error stack:

WARN  o.a.d.e.p.l.partition.PruneScanRule - Exception while trying to prune 
partition.
