On CDP we are using both the Hive (for the Hive Metastores) and Hive on Tez (for the HiveServers).
We are getting the below error while trying to run a query based on a condition. I can't share the table information and the exact query but it looks something as below.
CREATE EXTERNAL TABLE IF NOT EXISTS XXX (
`1` string,
`6` varchar(30),
`7` varchar(5),
`8` varchar(10)
) STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
WITH SERDEPROPERTIES('hbase.columns.mapping'=':key,
xx:1,
xx:5,
xx:6')
TBLPROPERTIES (
'hbase.table.name'='YYYYY'
);
the query looks as follows:
select * from XXX where 8 = '1990-10-10';
And we see the below error from the HiveServer

We added the below config on the HiveServer (based on this: https://community.cloudera.com/t5/Support-Questions/HIVE-concurrency-request-erreur-when-run-several...) but still, we are getting the issue.
