Hi all,
I am trying to setup an external metastore using Microsoft SQL on Azure, it
works ok initially but after about 5 mins inactivity it hangs, then times
out after 15 mins with this error:
15/05/20 00:02:49 ERROR ConnectionHandle: Database access problem. Killing
off this connection and all remaining connections in the connection pool.
SQL State = 08S01
15/05/20 00:02:49 ERROR RetryingHMSHandler: Retrying HMSHandler after 1000
ms (attempt 1 of 1) with error: javax.jdo.JDODataStoreException: SQL Server
did not return a
response. The connection has been closed.

I have also tried replacing BoneCP with DBCP in
datanucleus.connectionPoolingType, that didn't help either.
