General HPCC Systems Cross Platform Issues

NewEncountering an issue where embedded Java fails

The platform does not currently always enforce a Java Development Kit (JDK) dependency and the embedded Java plugin (javaembed) can fail if a JDK is not available. If you encounter this error, install the appropriate JDK for your Ubuntu distro or the openjdk-devel package for Centos.

Roxie worker threads were incorrectly given elevated priority if started on demand

In HPCC Systems 8.0.x series, an issue which could cause CPU starvation or other difficult to predict effects has been fixed. In this case, ROXIE was not operating as intended. While there is a work around available for earlier versions of HPCC Systems which involves setting the prestartAgentThreads option to true in the ROXIE configuration, it is now fixed and more details are available in this JIRA issue below:
