Known Issues and Limitations in Cloudera Manager 6.0.1

Backup and Disaster Recovery (BDR) performance regression after upgrading to CDH 6.0.0

Hive replication with BDR experiences a performance regression when comparing CDH 6.0.0 and CDH 5.14.4. The slowdown occurs during the import step. For example, the performance regression may only be 10% for 4 million partitions. As the number of partitions goes down though, the performance impact becomes more visible. For example, 100,000 partitions may experience a 20% performance regression.

Affected Versions: Cloudera Manager 6.0.0 and CDH 6.0.0; Cloudera Manager 6.0.1 and CDH 6.0.1

Externally authenticated users cannot view their roles or previous session

Usually, a user can see their assigned roles and most recent successful login by navigating to <Username> > My Profile in the Cloudera Manager Admin Console. The fields appear blank for users who use an external authentication method, such as SAML.

This issue is only a display issue and does not affect any functionality. The user can perform any tasks available to their assigned roles.

Workaround: User accounts with roles that can view the Roles page, such as a Full Administrator, can view the roles assigned to all Cloudera Manager user accounts and their session information.
