Hi - Did you happen to upgrade the 2.6 cluster to 3.0? If so, this may be due to the versioned data directory not getting the updated service definition for zeppelin.
Locate the previous version and the new version data directories and track down the zeppelin service definitions within data/services/zeppelin and compare the rewrite rules.
