--------------------------------
Summary: Column statistics on a partitioned column should fail
early with proper error message
Key: HIVE-5240
URL: https://issues.apache.org/jira/browse/HIVE-5240
Project: Hive
Issue Type: Bug
Components: Statistics
Affects Versions: 0.12.0
Reporter: Prasanth J
Assignee: Prasanth J
Fix For: 0.12.0
Attachments: HIVE-5240.txt
When computing column statistics on a partitioned table, if one of the columns
equals the partitioned column then IndexOutOfBoundsException is thrown.
Following analyze query throws IndexOutOfBoundsException during semantic
analysis phase
{code}hive> analyze table qlog_1m_part partition(year=5) compute statistics for
columns year,month,week,type;
FAILED: IndexOutOfBoundsException Index: 1, Size: 0{code}
If the partitioned column is specified at last like below then the same
exception is thrown at runtime
{code}hive> analyze table qlog_1m_part partition(year=5) compute statistics for
columns month,week,type,year;
