hellobabygogo opened a new issue #7763: Druid 0.12.3 - Middle Managers - NullPointerException Jackson
URL: https://github.com/apache/incubator-druid/issues/7763
Hi, all
We are running Druid 0.12.3 on production. Every hour we run approximately 2000 tasks on middle managers.
Every few hours one or two real time index tasks are failing with the same error:

I see someone also meet this problem and He thought this is is a issue of curator : https://github.com/apache/curator/commit/cc30b67c8dbe24babd31ed654e9536fe776b8a18.
how about merge this patch or replace our curator version?
