Though Darren is certainly correct that CM does not natively support upgrades between 5b1 and 5b2, it can be done with some extra manual steps involved. Here's what you would do:   Stop CDH5b1 cluster in CM5b1. Stop Cloudera Monitoring Services. Upgrade CM to 5b2. Start CM Upgrade CDH to 5b2 (for packages - manually, for parcels - using CM UI). If upgrading using parcels, DO NOT start the cluster. (Only if YARN is present in secure cluster) Goto “Settings” > “Administration”, Select ALL “yarn” principals and hit “Regenerate”. Wait for the “Generate Credentials” command to finish. This is needed because CDH5b2 added the HTTP principal for YARN. Start ZooKeeper Run HDFS Metadata Upgrade command from HDFS Actions Menu Run Oozie Database Upgrade command from Oozie Actions Menu Run Oozie Install Sharelib command from Oozie Actions Menu Run Upgrade Sqoop command from Sqoop Actions Menu Run Upgrade Hive Metastore Database Schema command from Hive Actions Menu Start all services Deploy Client Configuration for the cluster. Start Cloudera Monitoring Services. Hope this helps.   Best, Aaron ... View more
