[jira] [Updated] (DRILL-1547) Selecting records with multiple null
fields fails with AssertionError
[ https://issues.apache.org/jira/browse/DRILL-1547?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Hanifi Gunes updated DRILL-1547:
--------------------------------
Description:
If reader hits a records with multiple `null` valued fields whose vectors are not yet allocated, running capacity check twice throws AssertionError.
Take
{panel:title=a.json}
\{"some":null, "field": null\}
{panel}
Running
{code:sql}
select * from dfs.`a.json`
{code}
fails with AssertionError.
The work around is to check value capacity only if vector is allocated. This is an issue that affects sparse JSON files.
