autopurge config not showing up in echo conf

[Yuntong Qu]

Hi team,

I have zk setup and autopurge enabled, and I confirm that in zoo.cfg that I
have config below,  *autopurge.snapRetainCount = 12*
*autopurge.purgeInterval = 10*

also the zk log showing purge task started.

However, when I echo conf on this zk, autopurge didn't show up, is that
expected?

Thanks,
Yuntong
