Rushabh S Shah commented on HDFS-13314:
---------------------------------------
bq. Checkpointing is done by the standby.
But I don't need to restart the standby to do the checkpointing.
Standby does the checkpointing every 12 hours (in our case).
It will continue to write the corrupted image every 12 hours (and old images
won't be purged) if we don't upgrade the cluster in a month.
Am I missing something ?

> This behavior is controlled via an undocumented configuration setting, and
