Victoria Markman created DRILL-1910:
---------------------------------------
Summary: ROW_NUMBER() window function throws exception during execution
Key: DRILL-1910
URL: https://issues.apache.org/jira/browse/DRILL-1910
Project: Apache Drill
Issue Type: New Feature
Components: Functions - Drill
Affects Versions: 0.8.0
Reporter: Victoria Markman
Window function ROW_NUMBER() is currently:
* Supported in Calcite
* Not supported in DRILL
* Not documented in DRILL documentation
It throws exception during execution:
{code}
0: jdbc:drill:schema=dfs> select a1, row_number() over (partition by a1) from `t.json`;
Query failed: Query failed: Unexpected exception during fragment initialization: null
Error: exception while executing query: Failure while executing query. (state=,code=0)
0: jdbc:drill:schema=dfs> select a1, row_number() over () from `t.json`;
Query failed: Query failed: Unexpected exception during fragment initialization: null
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}
According to Jira, DRILL-1487 is targeted for 0.8.0 release.
DRILL-1902 is marked as critical bug as well.
We have two options:
1) Make this function work for 0.8.0
2) Throw unsupported error message in 0.8.0 and implement row_number() later
If we decide to go with option #1, can we please file a separate bug for error message
in 0.8.0 and turn this one into an enhancement request.
