Alexander Kolbasov commented on SENTRY-1916:
--------------------------------------------
[~vamsee] What is the point of storing the full snapshot if we are not going to
send it? The idea is to truncate on both sides - when we receive it from HMS
and when we send to NameNode - this allows us to conserve memory in both cases.
> Sentry should not store paths outside of the prefix

> Before Sentry 2.0 we were only sending paths which were inside Hive prefix to
> HDFS. With Sentry HA we changed that and store all paths. This significantly
> increases the amount of memory when there are many external tables.
