Subject Large number of application attempts

Hi all,
I have HBase cluster. 
I run a cron job each hour to create a snapshot of tables in HBase and export these snapshots
to another HBase cluster for backup. 
But I’ve noticed that there are ~4000 znodes in /hadoop-ha/testhbase1/rmstore/ZKRMStateRoot/RMAppRoot
in Zookeeper.
What are these znodes? 
Are they failed yarn applications?
How I need to handle them?

Thank you.
