Kudu 1.0.1 released today

Cloudera is happy to announce the availability of parcels and packages for Apache Kudu 1.0.1. Apache Kudu 1.0.1 is a bug fix release, with no new features or backwards incompatible changes.

To upgrade Kudu to 1.0.1, see Upgrade Parcels or Upgrade Packages.

Issues Fixed in Kudu 1.0.0

See Issues resolved for Kudu 1.0.1 and Git changes between 1.0.0 and 1.0.1.

  • KUDU-1681: Fixed a bug in the tablet server which could cause a crash when the DNS lookup during master heartbeat failed.

  • KUDU-1660: Fixed a bug which would cause the Kudu master and tablet server to fail to start on single CPU systems.

  • KUDU-1652: Fixed a bug that would cause the C++ client, tablet server, and Java client to crash or throw an exception when attempting to scan a table with a predicate which simplifies to IS NOT NULL on a non-nullable column. For example, setting a '<= 127' predicate on an INT8 column could trigger this bug, since the predicate only filters null values.

  • KUDU-1651: Fixed a bug that would cause the tablet server to crash when evaluating a scan with predicates over a dictionary encoded column containing an entire block of null values.

  • KUDU-1623: Fixed a bug that would cause the tablet server to crash when handling UPSERT operations that only set values for the primary key columns.

  • Gerrit #4488: Fixed a bug in the Java client's Kudu Exception class which could cause an unexpected NullPointerException to be thrown when the exception did not have an associated message.

  • KUDU-1090: Fixed a bug in the memory tracker which could cause a rare crash during tablet server startup.

For a complete list of new features, changes, bug fixes, and known issues, see the Kudu 1.0.1 Release Notes .
