Vamsee Yarlagadda commented on SENTRY-1919:
-------------------------------------------
This can only be achieved in the context of single sentry server right. i.e we
should make sure a single sentry server doesn't serve more than two HDFS
requests at the same time.
> Sentry should prevent two snapshots from being sent to HDFS

> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 2.0.0
> Reporter: Alexander Kolbasov
>
> When HDFS sync and HDFS HA is enabled it could be possible that two NameNodes
> will both ask for the full snapshot at the same time. This can double the
> size of memory needed to serve snapshot and should be prevented.
