We are happy to announce Kudu 0.6.0, the second beta release of Kudu, the industry’s first columnar storage manager developed for the Hadoop ecosystem.
This release includes the following fixes and enhancements:
-
The Java client's CreateTableBuilder and AlterTableBuilder classes have been renamed to CreateTableOptions and AlterTableOptions. Their methods now also return these objects, allowing them to be used as builders.
-
The Java client's AbstractKuduScannerBuilder#maxNumBytes() setter is now called batchSizeBytes, as is the corresponding property in AsyncKuduScanner. This makes it consistent with the C++ client.
-
The kudu-admin tool can now list and delete tables:
kudu-admin list
kudu-admin delete <table_name>
For a full list of issues addressed in Kudu 0.6.0, see this JIRA query.

Kudu already has an extensive set of capabilities, but there’s still work to be done and we’d appreciate your help. Kudu is fully open-source software, licensed under the Apache Software License 2.0. Additionally, we recently submitted Kudu to the Apache Software Foundation as an Apache Incubator project to help foster its growth and facilitate its usage.
As part of the open beta, we encourage the community to try it out. Here is how you can get started:
-
Download and install Kudu.
-
You need CDH 5.4.0 or higher and Cloudera Manager 5.4.3 or higher to try Kudu with CDH. Cloudera Manager 5.4.7 and higher provides additional administrative and monitoring options. Kudu requires either RHEL/CentOS 6.4 or later, or Ubuntu Trusty.
-
Installation via parcels with Cloudera Manager is simple and provides additional monitoring and administrative functionality. Kudu can also be installed using a Quickstart VM or through the command line using packages.
Once you get started, we’d love to hear your feedback:
Our team is excited about the possibilities that Kudu enables and we look forward to hearing about your experiences with Kudu.
