Problems with Kylin interface

[BELLIER Jean-luc <je...@rte-france.com>]

Hello,

I have moved my Kylin application to another node on my cluster. I am currently facing tow problems :

Exception in thread "Thread-13" java.lang.RuntimeException: java.lang.IllegalStateException: Cannot start job scheduler due to lack of job lock. I can also see messages like "java.lang.RuntimeException: Error while peeking at /kylin/kylin_metadata/job_engine/global_job_engine_lock".
I do not know if both problems are linked or not. The consequence is that in Kylin interface, the models cannot be loaded.
Nothing is displayed in the configuration. I attach the last versions of kylin.log and kylin.out files.

It is really a mystery for me. I really do not know if something is wrong in my kylin configuration, of if it comes from the node configuration.

Any help would be greatly appreciated.

Thank you in advance for your help.

Have a good day.

Best regards,
Jean-Luc.

Do you have another Kylin instance running? When Kylin starts up, it will
acquire a lock on Zookeeper; When another starts up, its job engine will do
the same and then fail if the lock wasn't released.
