Hi Razee, this issue at startup is improved a lot in CDH 5.15, see https://www.cloudera.com/documentation/enterprise/release-notes/topics/kudu_release_notes.html#relnotes_5_15_0 From that page: The strategy Kudu uses for automatically healing tablets which have lost a replica due to server or disk failures has been improved. The new re-replication strategy, or replica management scheme, first adds a replacement tablet replica before evicting the failed one. With the previous replica management scheme, the system first evicts the failed replica and then adds a replacement. The new replica management scheme allows for much faster recovery of tablets in scenarios where one tablet server goes down and then returns back shortly after 5 minutes or so. The new scheme also provides substantially better overall stability on clusters with frequent server failures. See KUDU-1097 for more information. Mike
