[GitHub] [ozone] adoroszlai opened a new pull request, #4200: HDDS-7820. Store container descriptor at start of tar archive
adoroszlai opened a new pull request, #4200:
URL: https://github.com/apache/ozone/pull/4200
## What changes were proposed in this pull request?
`DownloadAndImportReplicator` extracts container descriptor (`container.yaml`) as a first step when importing the container.
> A tar file isn't really indexed, and it doesn't have a "directory listing" section to list the files in it, it skips from one file header to the next seeking down the file. So if this file is always at the end, it must check all other file headers in the archive first.
Currently the descriptor is stored at the end of the tarball, so the import process needs to read the entire tarball twice.
This change moves the descriptor to the start of the archive.
https://issues.apache.org/jira/browse/HDDS-7820
## How was this patch tested?
Added an assertion about position of the descriptor.
