Version 3.1.3

Released on 2018/11/19.

Note

If you are upgrading a cluster, you must be running CrateDB 2.0.4 or higher before you upgrade to 3.1.3.

We recommend that you upgrade to the latest 3.0 release before moving to 3.1.3.

If you want to perform a rolling upgrade, your current CrateDB version number must be at least Version 3.1.1. Any upgrade from a version prior to this will require a full restart upgrade.

Warning

Tables that were created prior to upgrading to CrateDB 2.x will not function with 3.1 and must be recreated before moving to 3.1.x.

You can recreate tables using COPY TO and COPY FROM while running a 2.x release into a new table, or by inserting the data into a new table.

Before upgrading, you should back up your data.

Fixes

  • Updated the Admin UI to 1.10.4 which includes the following fixes:
    • Fixed an issue that caused the cluster and node checks to not be refreshed when clicking on the refresh icon.
    • Fixed an issue that caused the Twitter importer to redirect to / instead of /help.
    • Fixed the navigation component to allow opening URLs in new tabs.
  • Fixed a race condition that could allow the creation of partitions with a different schema than other partitions within the same partitioned table.
  • Changed the user hdfs repository parameter to security.principal, as that is the parameter used by the underlying repository-hdfs plugin.
  • Removed the conf_location hdfs repository parameter as it is no longer used.
  • Fixed an issue that caused zombie entries in sys.jobs if the fetchSize functionality of postgres wire protocol based clients is used.
  • Fixed a memory leak in the MQTT ingest service.
  • Fixed a memory leak that could occur with clients connecting via postgres protocol and invoking read queries with statements containing expressions that would fail (such as 1 / 0).
  • Fixed an issue in the postgres wire protocol that could result in nodes crashing with OutOfMemoryError if clients queried very large tables without specifying the fetch size.
  • Fixed an issue that caused missing privilege errors if table aliases were used.
