Blocker Description
I was running test/system/upgrade_test.sh dirty and the test hung. Upon inspection, the wals from 1.5 were deleted before all tablets were recovered.
Some tablets from 1.5 recovered fine.

Then the GC kicked in and deleted files before tablets were finished recovering.

Tablet failed to recover.

I had set my gc delay to 30 secs while testing another issue and thats why I ran into this issue.
Looking at the code, I do not think its properly converting relative paths from 1.5 to absolute paths. I think the code should convert everything to relative paths (just UUIDs) to avoid problems caused by differing configurations.
