Falcon Upgrade/Downgrade Issue with ActiveMQ​

When upgrading to HDP 2.5 or later with Falcon, you might encounter the following error when starting the ActiveMQ server:


ERROR - [main:] ~ Failed to start ActiveMQ JMS Message Broker. Reason: java.lang.NegativeArraySizeException (BrokerService:528)

You might also encounter this error if downgrading Falcon from HDP 2.5 to an earlier release.

If you encounter this error, delete the ActiveMQ history and then restart Falcon. If you want to retain the history, be sure to back up the ActiveMQ history prior to deleting it.


cd <ACTIVEMQ_DATA_DIR>
rm -rf ./localhost

cd /usr/hdp/current/falcon-server

su -l <FALCON_USER>




./bin/falcon-stop

./bin/falcon-start
