> When use avatica connect Phoenix QueryServer, I create an AvaticaConnection:
> {code:java}
> Connection conntion = DriverManage.getConnection(url);
> connection.setAutoCommit(true);
> {code}
> Avatica keep PhoenixConnection alive in the Cache, which will be expired after 10min by default.
> I still use the older AvaticaConnection , it will reopen an PhoenixConnection, but the ConnectionProperties is loss, such as AutoCommit.
> I use sqlline-thin.py to reappear the problem:
> 1) sqlline-thin.py http://localhost:8765
> 2) upsert one row and select
>  !image-2019-02-28-17-25-39-478.png! 
> 3) after 10 min, upsert again, the connection will be recreate, but select null
