https://community.cloudera.com/t5/Support-Questions/Hive-overwrites-existing-external-table-data/m-p/231860#M193703 <P>Hello <A href="https://community.hortonworks.com/questions/155477/hive-overwrites-existing-external-table-data.html#">@Bala Vignesh N V</A> thank you for your reply and my excuses for the insufficient information but I missed out to mention that in our case we have this behavior on HDFS not S3. Also I really want to avoid such a union because our inserts are already invoking huge select with join so this work around would exhaust our cluster resources and would make the ETL process really slow. Are you aware of such a bug? or it could be a configuration issue as well?</P> Fri, 29 Dec 2017 18:43:42 GMT abiratsis 2017-12-29T18:43:42Z
