> Snapshot Bootstrap creates incorrect hard links.
> ------------------------------------------------

> Key: HDDS-9207
> URL: https://issues.apache.org/jira/browse/HDDS-9207
> Project: Apache Ozone
> Issue Type: Bug
> Components: Snapshot
> Reporter: George Jahad
> Assignee: George Jahad
> Priority: Blocker
> Labels: pull-request-available
>
> The Snapshot bootstrap tarball creation code was incorrectly assuming that
> two sst files with the same name, (but different directories,) were hard
> linked to each other.
> This assumption will not be true in cases, like the following, where the
> files are initially created in different rocksdb directories. For example:
> 1. Suppose the active fs and snap1 consist of sst files: s1.sst-s10.sst.
> 2. Then some delete records get added to snap1. Those get put into s11.sst.
> 3. Meanwhile more keyTable entries are added to the active fs; they could get
> put into a different file named also s11.sst.
> To remedy this, the tarball creator must check the INodes of each file to
> confirm they are equal before linking them together.
