Upgrade Notes for Kudu 1.5.0 / CDH 5.13.0 and Higher

  • Kudu 1.5 enables the optional ability to compute, store, and verify checksums on all pieces of data stored on a server by default. Due to storage format changes, downgrading to versions 1.3 or earlier is not supported and will result in an error.

  • The kudu-spark-tools module has been renamed to kudu-spark2-tools_2.11 in order to include the Spark and Scala base versions. This matches the pattern used in the kudu-spark module and artifacts.

  • To improve security, world-readable Kerberos keytab files are no longer accepted by default. Set --allow_world_readable_credentials=true to override this behavior. See KUDU-1955 for additional details.
