Alex Petrov commented on CASSANDRA-11887:
-----------------------------------------
True. Would it be possible for you to try copying sstables (one or multiple) to
local node and trying to delete (with or without flush, but without compaction)
while already running 3.x version (preferrably same version that was mentioned
when ticket was created, 3.0.6)? Symptoms of [CASSANDRA-12144] were that
duplicate rows were becoming undeletable.
Also, if you could run upgrade and dump same sstable with {{sstable2json}} to
see what they start looking like on 3.0.
Maybe we can debug it this way. Thank you for your time.
