----------------------------------
Summary: Kylin treat empty string as error measure which is inconsistent with hive
Key: KYLIN-2288
URL: https://issues.apache.org/jira/browse/KYLIN-2288
Project: Kylin
Issue Type: Bug
Components: Metadata
Affects Versions: all
Reporter: Chuanlei Ni
Assignee: Shaofeng SHI
Assume we have a hive table
name, age
tom, 10
jack, (empty string)
if we execute
select count(age) from thistable;
we can get 10 as the result. (my hive version is 0.13.1)
But Kylin can build cube for this case as BigDecimalIngester/DoubleIngester/LongIngester cannot recongnize empty string
