Navis created HIVE-3401:
---------------------------
Summary: Diversify grammar for split sampling
Key: HIVE-3401
URL: https://issues.apache.org/jira/browse/HIVE-3401
Project: Hive
Issue Type: Improvement
Components: Query Processor
Reporter: Navis
Assignee: Navis
Priority: Trivial
Current split sampling only supports grammar like TABLESAMPLE(n PERCENT). But
some users wants to specify just the size of input. It can be easily calculated
with a few commands but it seemed good to support more grammars something like
TABLESAMPLE(500M).
