Herman Chen updated IMPALA-8335: -------------------------------- Summary: Avro support requires field names to be all lowercase (was: Avro support requires all lowercase fields) > Avro support requires field names to be all lowercase > ----------------------------------------------------- > > Key: IMPALA-8335 > URL: https://issues.apache.org/jira/browse/IMPALA-8335 > Project: IMPALA > Issue Type: Question > Components: Catalog, Docs > Reporter: Herman Chen > Priority: Major > > I am using external tables where the data resides in S3 in avro format. My > avdl contains fields such as: > string id; > string sql; > string templateId; > union \{ null, string } pool; > union \{ null, string } user; > string startTime; > string endTime; > However, Impala is able to read the all-lowerfields like "id" and "sql", but > for any field containing uppercase like "templateId" or "startTime", Impala > shows them all as NULL. I believe this is due to how Impala treats all > identifier as lowercase, including column name. Is it so? Is there any way to > work around it? If not it poses a major roadblock for working with > pre-existing avro data. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
