> When browser based SSO is enabled the Hive JDBC driver might miss the POST 
> requests coming from the browser which provide the one-time token issued by 
> HS2s after the SAML flow completes. The issue was observed mostly in virtual 
> environments on Windows.
> The issue seems to be that when the driver binds to a port even though the 
> port is in LISTEN state, if the browser issues posts request on the port 
> before it goes into ACCEPT state the result is non-deterministic. On native 
> OSes we observed that the connection is buffered and is received by the 
> driver when it begins accepting the connections. In case of VMs it is 
> observed that even though the connection is buffered and presented when the 
> port goes into ACCEPT mode, the payload of the request or the connection 
> itself is lost. This race condition causes the driver to wait for the browser 
> until it timesout and the browser keeps waiting for a response from the 
> driver.
