Solutions

1. Start re-encryption for the zone first ('hdfs crypto -reencryptZone -action start'), or check that the zone name is correct.

When it happens

Trigger: A re-encryption tracking/commit step references an encryption zone with no active re-encryption.

Common situations: Running reencryption finalize/cancel on a zone that was never started or already completed.
