JyotinderSingh opened a new pull request #3227: URL: https://github.com/apache/ozone/pull/3227
## What changes were proposed in this pull request? OmMetadataManagerImpl#isBucketEmpty only checks the key table. This means it is possible to delete an FSO bucket that still has data, orphaning the remaining data on the OM. This patch adds a new code path for File System Optimized buckets. In the case of FSO layout, we check the directory and file tables for any entries that might be present under the said bucket. In buckets with FSO layout, the metadata entry for a - **Top-level directory** would be of the format `<bucket ID>/dirName` inside the `dirTable`. - **Top-level file** (a file directly placed under the bucket without any sub paths) would be of the format `<bucket ID>/fileName` inside the `fileTable`. We seek any keys in these tables that begin with the requested bucket's ID - if we find any such entries in the table or the table cache, we return False. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-6425 ## How was this patch tested?
