Installation and Upgrade Changes

Installation or Upgrade of Cloudera Manager 6.3.3 and CDH 6.3.3 now requires authentication to access downloads

Beginning with Cloudera Manager and CDH 6.3.3, downloading new versions of these products will require a valid Cloudera Enterprise license file, and/or a username and password obtained from Cloudera. All Cloudera Manager package, CDH parcel and CDH package repositories now require authentication with valid credentials to access any version numbered 6.3.3 or later. For more information on using these credentials, see the documentation below.

Cloudera Express has been discontinued

Beginning with CDH 6.3.3 (and CDP Data Center 7.0), Cloudera Express is no longer available. Upgrades to Cloudera Manager or CDH 6.3.3 and higher are not supported when running Cloudera Express. A valid Cloudera Enterprise or CDP Data Center license must be in place before upgrading to Cloudera Manager 6.3.3 or 7.x or the upgrade will not be completed.

Downgrading from Cloudera Enterprise license to Cloudera Express license is also no longer supported in Cloudera Manager 6.3.3 and higher.

Support for RHEL 7.7

Cloudera Manager 5.16, 6.0.1, 6.1.1, 6.2.1, and Cloudera Manager 6.3.3 or higher are now certified for RHEL 7.7.

Parallel metrics roll-up

To improve performance, roll-up of monitoring metrics can now run in parallel by setting the following configurations in the Service Monitor Advanced Configuration Snippet:
  • firehose.timeseries.rollup.num.threads – The default value is 1. Increase the value to improve performance.
  • firehose.timeseries.rollup.delay.minutes – The default value is 0. Increase the value to improve performance.

Cloudera recommends trying the following settings to improve performance:

firehose.timeseries.rollup.num.threads=3 
firehose.timeseries.rollup.delay.minutes=15
