-----------------------------------
Summary: Create Kudu table syntax does not allow multi-column
range partitions
Key: IMPALA-6929
URL: https://issues.apache.org/jira/browse/IMPALA-6929
Project: IMPALA
Issue Type: Bug
Components: Frontend
Affects Versions: Impala 2.11.0
Reporter: Dan Burkert
The Impala CREATE TABLE syntax guide includes this bit of grammar in the Kudu
partitioning section:
{code:java}
range_clause ::=
RANGE [ (pk_col [, ...]) ]
(
{
PARTITION constant_expression range_comparison_operator VALUES
range_comparison_operator constant_expression
| PARTITION VALUE = constant_expression_or_tuple
}
[, ...]
){code}
This is suspicious because {{constant_expression}} is used in the range clause,
and {{constant_expression_or_tuple}} is used in the single-value clause. I
believe both should allow for tuples.
In other words, today a CREATE TABLE statement such as
{code:java}
CREATE TABLE t (a BIGINT, b BIGINT, PRIMARY KEY (a, b))
PARTITION BY RANGE (a, b) (
PARTITION (0, 0) <= VALUES < (10, 0)
) STORED AS KUDU;{code}
results in a syntax error, and it should not. CC [~twmarshall]
