Symptoms

After performing a Datameer upgrade from a version earlier than 4.3.0 to 4.3.0 or newer, the following error message is observed in the conductor log when first starting Datameer:

[anonymous] ERROR [2014-01-01 00:00:00.000] [main] (ContextLoader.java:227) - Context initialization failed
org.springframework.beans.factory.access.BootstrapException: Unable to initialize group definition.

The anychart plugin was found to be included in some version of Datameer which were built with libraries for CDH 3u4.

Cause

The cause of this error is that the das.anychart plugin is being loaded by Datameer. Support for this plugin was deprecated starting in Datameer 4.3.

Solution

Please follow these steps to restart Datameer without including the das.anychart plugin.

1. Stop Datameer
2. Delete the following files if they exist in the Datameer installation directory

rm etc/custom-jars/dap-anychart-2.1.1.jar
rm job-jar/das-custom-jar-dap-anychart-2.1.1.jar
rm webapps/ROOT/WEB-INF/lib/das-custom-jar-dap-anychart-2.1.1.jar

3. Start Datameer
