This only happen when authenticating against LDAP.
I have known the invalid sasl status reason, which is caused by a misconfigured
tableau client. When I run the test code, there is a tableau connection to
access impala service which is periodically refreshed by tableau server. The
client is configured to use http authentication protocol to access 21050 port.
Once the refresh happen, impalad thrift server will report invalid sasl status
and it will hang all thrift client.
But I don't know why one client is misconfigured, it will cause all clients
hang for serval minutes, which may be a bad design. I check the impalad
TAcceptQueueServer source code, which seems to use one thread to deal with
authentication connection.

Does this only happen when authenticating against LDAP?
Do the errors occur on every run? I wonder if this is related to running out of
TCP ports because they're all still stuck in TIME-WAIT, waiting to be closed.

[~kwho] [~lv] this is interesting - I guess maybe this is a similar symptom to
the other case where the thrift server gets tied up?
