General HPCC Systems core platform

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.

Ensure non-OPT KEYED fields after a wild match are keyed fix included in 7.12.30

This change restores the behaviour of keyed limits to match HPCC Systems 6.x x and earlier releases. But it may therefore, change the behaviour of queries previously deployed using HPCC Systems 7.x.x the next time they are compiled. There is a new global option that can be used to select the 7.x .x behaviour if you want to avoid the changed behaviour when recompiling 7.x.x queries. More detailed information is provided in the JIRA issue.

Data Patterns collected for a Thor file stay unchanged after the file is overwritten

The fix for this issue may mean any previously created Data Pattern reports (in ECL Watch) will need to be re-created.
