Hi Eva,
Can you open a new jira for this? And let’s discuss and resolve this
issue.
I guess this is because the partition metadata is added before the data is
available.
Thanks

Hi Eva,
After a close at the code, I think this is not a bug. We need to find out
how to avoid this.
Thanks,

Prasad,
We believe the problem is that one of the query is doing an ‘insert overwrite
... select from’ which actually is deleting and merging the small files. The
other query somehow

Hi Prasad,
Are you implying the expected behavior for these queries should be run
sequentially by hive because one is r/w and one is read-only ?
For
locking (possibly with HDFS files) to prevent

Regardless of whether the user uses a HiveServer, looks like the logical place
to do locking or concurrency control would be at the metastore DB
