[main-SendThread(localhost:2181):SaslClientCallbackHandler@60] - Could not
login: the Client is being asked for a password, but the ZooKeeper Client code
does not currently support obtaining a password from the user. Make sure that
the Client is configured to use a ticket cache (using the JAAS configuration
setting 'useTicketCache=true)' and restart the Client. If you still get this
message after that, the TGT in the ticket cache has expired and must be
manually refreshed. To do so, first determine if you are using a password or a
keytab. If the former, run kinit in a Unix shell in the environment of the user
who is running this Zookeeper Client using the command 'kinit <princ>' (where
<princ> is the name of the Client's Kerberos principal). If the latter, do
'kinit -k -t <keytab> <princ>' (where <princ> is the name of the Kerberos
principal, and <keytab> is the location of the keytab file). After manually
refreshing your cache, restart this Client. If you continue to see this message
after manually refreshing your cache, ensure that your KDC host's clock is in
sync with this host's clock. 2020-08-17 13:58:18,604 - WARN
