             Summary: impala-shell -b / --kerberos_host_fqdn flag overrides value passed in via -i
                 Key: IMPALA-7130
                 URL: https://issues.apache.org/jira/browse/IMPALA-7130
             Project: IMPALA
          Issue Type: Bug
          Components: Clients
    Affects Versions: Impala 2.12.0, Impala 3.0
            Reporter: Vincent Tran
            Assignee: Vincent Tran


When impala-shell -b / --kerberos_host_fqdn is used, the value will override one passed in via -i / --impalad.
This leads to the socket being created with the former value in the case when -b is used.

The problematic section of code is here

{noformat}
    if self.kerberos_host_fqdn is not None:
      host, port = (self.kerberos_host_fqdn.split(':')[0].encode('ascii', 'ignore'),
            int(self.impalad[1]))
    else:
      host, port = self.impalad[0].encode('ascii', 'ignore'), int(self.impalad[1])
    if self.use_ssl:
      if self.ca_cert is None:
        # No CA cert means don't try to verify the certificate
        sock = TSSLSocketWithWildcardSAN(host, port, validate=False)
      else:
        sock = TSSLSocketWithWildcardSAN(host, port, validate=True, ca_certs=self.ca_cert)
    else:
      sock = TSocket(host, port)
    if not (self.use_ldap or self.use_kerberos):
      return TBufferedTransport(sock)
{noformat}

The proposed fix is to always create the socket with the host passed in via -i
{noformat}
self.impalad[0].encode('ascii', 'ignore')
{noformat}
