------------------------------------------
> Browser SSO auth may fail intermittently on chrome browser in virtual

> ----------------------------------------------------------------------------------
>
> Key: HIVE-25479
> URL: https://issues.apache.org/jira/browse/HIVE-25479
> Project: Hive
> Issue Type: Bug
> Components: JDBC
> Reporter: Vihang Karajgaonkar
> Assignee: Vihang Karajgaonkar
> Priority: Major
>
> 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.
