Anurag Mantripragada resolved IMPALA-9116. ------------------------------------------ Assignee: Anurag Mantripragada Resolution: Fixed > SASL server fails when FQDN is greater than 63 characters long in Kudu RPC > -------------------------------------------------------------------------- > > Key: IMPALA-9116 > URL: https://issues.apache.org/jira/browse/IMPALA-9116 > Project: IMPALA > Issue Type: Bug > Components: Backend > Affects Versions: Impala 3.3.0 > Reporter: Anurag Mantripragada > Assignee: Anurag Mantripragada > Priority: Critical > Fix For: Impala 3.4.0 > > > In the current Kudu RPC implementation, we don't explicitly pass the host's > FQDN into the SASL library. Due to an upstream SASL bug > ([https://github.com/cyrusimap/cyrus-sasl/issues/583]) the FQDN gets > truncated when trying to determine the server's principal, in the case that > the server's fQDN is longer than 64 characters. > This results in startup failures where the preflight checks fail due to not > finding the appropriate keytab entry (after searching for a truncated host > name) > To work around this, we should use our own code to compute the FQDN. > Kudu is making the changes in it's own implementation here: > https://issues.apache.org/jira/browse/KUDU-2989, we should do the same. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
