Hi CDH, Cloudera Manager, and Cloudera Navigator users,We’re pleased to announce the release of Cloudera Enterprise 5.4 (comprising CDH 5.4, Cloudera Manager 5.4, and Cloudera Navigator 2.3).Cloudera Enterprise 5.4 (Release Notes) reflects critical investments in a production-ready customer experience through governance, security, performance and deployment flexibility in cloud environments. It also includes support for a significant number of updated open standard components–including Apache Spark 1.3, Impala 2.2, and Apache HBase 1.0 (as well as unsupported beta releases of Hive-on-Spark data processing and OpenStack deployments).Recently Cloudera made the upgrade process considerably easier via an improved CDH upgrade wizard; see details about that wizard here and best practices here. (Note: Due to metadata format changes in Apache Hadoop 2.6, upgrading to CDH 5.4 and later from any earlier release requires an HDFS metadata upgrade, as well. Note also that for parcel-based installs of CDH 5.4, Cloudera Manager 5.4 is required.)SecuritySSL and Kerberos support in Apache Flume for the Thrift source and sink.SSL support across Cloudera Search (Solr and all integrations with CDH).Cluster-wide redaction of sensitive data in logs is now possible.HBase impersonation in Hue allows your client to authenticate to HBase as any user, and to re-authenticate at any time.Solr metadata stored in ZooKeeper can now be protected by ZooKeeper ACLs.Kerberos is now supported for Apache Sqoop2.PerformanceIncludes beta release of Hive-on-Spark as an option for improved Hive data processing performance (unsupported).MultiWAL support for HBase RegionServers allows you to increase throughput when a region writes to the write-ahead log (WAL).You can now store medium-sized objects (MOBs) up to 10MB in size directly in HBase while maintaining read and write performance.A new Kafka connector for Spark Streaming avoids the need for the HDFS WAL.Hue pages render much faster.Data Management and GovernanceExpanded coverage in Cloudera NavigatorImpala (CDH 5.4 and higher) lineageCloudera Search (CDH 5.4 and higher) auditingAuditing of Navigator activity, such as audit views, metadata searches, and policy editingAvro and Parquet schema inferencePlatform enhancementsRedesigned metadata search provides autocomplete, faster filtering, and saved searchesSAML for single sign-onCloud DeploymentsOpenStack deployments are now possible as an unsupported beta.HBase support on Microsoft Azure.Real-Time ArchitectureCloudera Distribution of Apache Kafka 1.3 installs by default and is supported for production use.Spark Streaming now has a receiver-less “direct” connector for Kafka.New or Updated Open Source ComponentsApache Hadoop 2.6Apache HBase 1.0Apache Hive 1.1Apache Oozie 4.1Apache Solr 4.10.3Apache Spark 1.3Cloudera Distribution of Apache Kafka 1.3Hue 3.7Impala 2.2Kite SDK 1.0New/Updated OS & Java SupportRHEL 6.6/CentOS 6.6/OEL 6.6 (UEK3)JDK8u40, JDK7u75Over the next few weeks, we’ll publish blog posts that cover some of these features in detail.

Ensure the Key HSM service is running: sudo service keyhsm start Establish trust from Key Trustee Server to Key HSM specifying the path to the private key and certificate (Key Trustee Server is a client to Key HSM). This example shows how to use the --client-certfile and --client-keyfile options to specify the path to non-default certificate and key: $ sudo ktadmin keyhsm --server \--client-certfile /etc/pki/cloudera/certs/mycert.crt \--client-keyfile /etc/pki/cloudera/certs/mykey.key --trust For a password-protected Key Trustee Server private key, add the --passphrase argument to the command and enter the password when prompted: $ sudo ktadmin keyhsm --passphrase \--server \--client-certfile /etc/pki/cloudera/certs/mycert.crt \--client-keyfile /etc/pki/cloudera/certs/mykey.key --trust Any keys that exist on the Key Trustee Server are automatically migrated when you run the ktadmin keyhsm command. To complete the migration, enter y or yes at the command prompt:Some deposits were found that will need to be moved to the HSM. Note that although this operation can be interrupted, once complete, items stored in the HSM must remain there!Do you want to perform this migration now?
