[jira] [Updated] (DRILL-2777) CTAS, order by and flatten of
repeated list result in ExpandConversionRule error
[ https://issues.apache.org/jira/browse/DRILL-2777?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rahul Challapalli updated DRILL-2777:
-------------------------------------
Description:
git.commit.id.abbrev=f066786
The below query results in an error :
{code}
create table dfs.ctas_flatten.`test` as select uid, flatten(lst_lst) lst, flatten(lst_lst[0]) from `data1.json` order by flatten(lst_lst[0]);
Query failed: IndexOutOfBoundsException: index (2) must be less than size (2)
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}
The logs indicate an assertion error :
{code}
Caused by: java.lang.AssertionError: Internal error: Error while applying rule ExpandConversionRule, args [rel#1757858:AbstractConverter.PHYSICAL.SINGLETON([]).[2](child=rel#1757856:Subset#8.PHYSICAL.ANY([]).[2],convention=PHYSICAL,DrillDistributionTraitDef=SINGLETON([]),sort=[2])]
{code}
The query itself does not have any issues. Also the below variants work :
{code}
1. No flatten of repeated list in the select clause
create table dfs.ctas_flatten.`test` as select uid, flatten(lst_lst[0]) from `data1.json` order by flatten(lst_lst[0]);
2. Removing the flatten from the order by. (Ordering by a scalar has no issues)
create table dfs.ctas_flatten.`test` as select uid, flatten(lst_lst) lst, flatten(lst_lst[0]) from `data1.json`;
{code}
Attached the data set and the complete error log file
was:
git.commit.id.abbrev=f066786
Summary: CTAS, order by and flatten of repeated list result in ExpandConversionRule error (was: CTAS, order by and flatten of repeated list result in IOOBException)
