> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Manager
> Reporter: Sumit Agrawal
> Assignee: Sumit Agrawal
> Priority: Major

> Fix For: 1.4.0

>
> When creating a large number of buckets using freon, 27.7 million buckets are
> created with OM configured with 32GB memory.
>
> Since bucket is full cache table, so all bucket information is kept in
> memory. This is consuming almost all memory of OM.
> Further (pause of GC) is happening when OM is about to reach OOM and no more
> memory available to be freed.
