Sylvain Lebresne commented on CASSANDRA-12351:
----------------------------------------------
Thanks for the analysis and patch, but 2 bugs due to CASSANDRA-11427, which is
minor in the first place, is way above my comfort level so reverted the whole
patch in commit f28631e0cf1bc6cb6a1bdf7a4fa1f4af720a77b6. I'd be happy if you
can confirm this fix your reproduction steps, but closing due to the revert in
the meantime.

> {{getSchemaPartitionsForTable(KEYSPACES)}} is now (since 2.2.6) returning
> more rows. The additional rows are empty.
> These rows are coming out of the row iterator post 2.2.6, where they were not
> in 2.2.6.
