Hive query does NOT return through ODBC
We are using Hortonworks ODBC driver 220.127.116.118 (64 bit) and HDP 2.2 for Windows Server.
One of our web service talks to Hive. It uses background threads to issue query through ODBC and distributed cache to store previous results.
The problem is, sometimes, queries to Hive through ODBC dose not return, so querying threads never end and cache will not be updated.
We checked TCP connections to HDP cluster and seems like no connection were made through ODBC for those querying threads.
If we restart app pool of web service everything can work properly again.
Our code is really simple, so does anyone also experience this or this is a known bug?
Any comments and suggestions are welcome.
