--------------------------------
Summary: NPE in ORC's PPD when using select * from table with where predicate
Key: HIVE-5601
URL: https://issues.apache.org/jira/browse/HIVE-5601
Project: Hive
Issue Type: Bug
Affects Versions: 0.12.0
Reporter: Prasanth J
Assignee: Prasanth J
Priority: Critical
ORCInputFormat has a method findIncludedColumns() which returns boolean array of included columns. In case of the following query
{code}select * from qlog_orc where id<1000 limit 10;{code}
where all columns are selected the findIncludedColumns() returns null. This will result in a NPE when PPD is enabled. Following is the stack trace
{code}Caused by: java.lang.NullPointerException
