Subject Re: A possible big bug: Delta files created by hive hcatalog streaming cannot be compacted!
Date Tue, 25 Nov 2014 20:37:25 GMT
Alan,
Thank you very much for the quick response. The hive jira: HIVE-8966 (
https://issues.apache.org/jira/browse/HIVE-8966) has been created.
This is really a big issue. We are using hive hcatalog streaming to
populate data into hive. It will be very bad if the data cannot be
compacted. So please fix it as early as possible.
Thank you very much for your help
Jihong
