Suppress error log on ObjectAlreadyExistsException

[konieshadow]

When schedule some job, I want to catch the ObjectAlreadyExistsException to determine whether exists a same job and then reschedule it. This works fine but the log output from RedisStorage is annoying. Like this:

2019-05-22 16:42:47.475  INFO 9064 --- [           main] n.joelinn.quartz.jobstore.RedisJobStore  : Job and / or trigger already exist in storage.

org.quartz.ObjectAlreadyExistsException: Unable to store Job : 'com.handarui.novel.server.biz.task.IndexUpdateNovelJob.indexUpdateNovel', because one already exists with this identification.

I wunder if it can be suppressed and just let user to handle the exception.
