Description

When dropping a table with a failed tablet, the tablet will fail to be deleted. The /tablets endpoint shows its Last Status as: Invalid argument: Unable to delete on-disk data from tablet 2e3b95dba81044748a9a52eb138dd59c: The metadata for tablet 2e3b95dba81044748a9a52eb138dd59c still references orphaned blocks. Call DeleteTabletData() first

Steps to repro:

1. Create a table with a single tablet, single replica.
2. Load enough data to have the WAL roll a segment
3. Corrupt the magic bytes of a non-current segment
4. Restart the TS
5. Drop the table
