Hello, I am not sure if this is the purpose of this email, but I couldn’t find any information on this elsewhere. We are using Kerberos MIT on some Windows servers with keytabs, in order to connect to our cloudera Impala server (that uses Kerberos authentication) We use around 3 principals in the same day on one server and it usually works without issues. But on occasion (twice so far), we get this error message on the Cloudera ODBC: Error: Connector connect error: SQL##f - SqlState: S1000, ErrorCode: 0, ErrorMsg: [Cloudera][KerberosSupport] (0) Error occurred during Kerberos library operation: Internal credentials cache error Upon accessing the machine locally & opening Kerberos Ticket Manager we get this message [cid:[email protected]]
From what we could tell, that error is actually: KRB5_CC_NOMEM -1765328186L 198 No more memory to allocate (in credentials cache code) (found here https://www.netmeister.org/blog/krb5-error-codes-table.html ) We fixed it by deleting the krb5cache file & restarted the Kerberos MIT ticket manager, but we would like to know what is causing this issue. We would appreciate any advice in identifying the cause of this issue and finding a fix for it. Thank you ! Kind regards / Cu stima, Șerban Panait Team Leader BI Core [73614]
