---------------------------------
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:
{code}
WARN o.a.d.e.p.l.partition.PruneScanRule - Exception while trying to prune
partition.
java.lang.IndexOutOfBoundsException: index: 4096, length: 1 (expected: range(0,
