Hi All,

Created a materialized view with partitions and
tblproperties('transactional'='true') in Hive Version 4.0 running on Hadoop
3.1. View gets created properly and I can see one file in each partition.
When we tried to query the view though no rows are getting returned.

In describe formatted, we see that numFiles and numRows are 0.
Tried gathering statistics, MSCK repair table etc and manually dropped and
re-added partition. Still the materialized view returns 0 rows.

Not quite sure if I am missing something or if this is a bug. Have attached
the output of describe and hive-server2 logs that got generated when the
materialized view was created.

Log shows below error message while gathering statistics:

MetaException(message:Cannot change stats state for a transactional table
without providing the transactional write state for verification (new write
ID 0, valid write IDs default.test_fact_mv:0:9223372036854775807::;

Can you please give me some pointers to get the above materialized view
working?

Thanks,
Karthik
