When the filter condition fails for all the records and we use flatten in the
query, then drill fails. i have tried this with more than one record
Data Set :
{code}
{
"id" : "01",
"id1" : 1,
"list" : [
{"col1":"0001","name":"nn001"},
{"col2":"0002","name":"nn02"}
]
}
{code}
Below query fails :
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select s.id, s.id1, flatten(s.list) fl
from `sample.json` s where s.id='02';
Query failed: Query failed: Failure while running fragment., index: -4, length:
4 (expected: range(0, 16384)) [ d2b028fe-2c0c-4652-be61-a93f08862883 on
qa-node190.qa.lab:31010 ]
[ d2b028fe-2c0c-4652-be61-a93f08862883 on qa-node190.qa.lab:31010 ]
{code}
Below is the error from the logs :
{code}
java.lang.IndexOutOfBoundsException: index: -4, length: 4 (expected: range(0,
16384))
