While we have enabled LDAP authentication for Impala (just for one of the Daemon nodes),and trying to connect to that node from impala shell (impala-shell -i <hostname> -s <service id> -l -u <userid>, we are getting the following error, but obviously it is not found in kerberos because we disabled kerberos. Looking around for some inputs, I am not sure if I am missing some fundamentals here
Starting Impala Shell using LDAP-based authentication
LDAP password for <user>:
Error connecting: TTransportException, TSocket read 0 bytes
Kerberos ticket found in the credentials cache, retrying the connection with a secure transport.
Error connecting: TTransportException, Could not start SASL: Error in sasl_client_start (-1) SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (Server /xxx not foundin Kerberos database)
Any inputs appreciated.
