Due to Kudu-2264, secure, long-running Impala clusters on CDH 5.13.x and later will be unable to interact with Kudu tables after some time because the Kudu client used by Impala will no longer be able to authenticate with Kudu. The problem starts after the client's ticket can no longer be renewed, which is typically after 7 days. Restarting the Impala service will allow Impala to work with Kudu again.

Products Affected: Impala

Releases Affected: CDH 5.13.0, CDH 5.13.1, and CDH 5.14.0

Users Affected: Users running a secure cluster with Impala and Kudu.

Severity: Medium

Impact: Impala will not be able to query or write to Kudu tables until the service is restarted. The Impala service will need to be restarted periodically in order to continue being able to work with Kudu tables.

Immediate action required: To work around the issue, users can restart the Impala service at least once per ticket renewal period. This period is typically 7 days.

Addressed in release: CDH 5.13.2, CDH 5.13.3, and CDH 5.14.2
