MultiNodeTableWalkWithReadRepairTest surfaces an AssertionError triggered by
merging range tombstones during read repair.
This failure reproduces on trunk at 1332e21 given a fixed seed.
// in MultiNodeTableWalkWithReadRepairTest.preCheck(...), set the seed to:
{{builder.withSeed(1873589047276343123L);}}
Then run:
{{ant test-jvm-dtest-some
-Dtest.name=org.apache.cassandra.distributed.test.cql3.MultiNodeTableWalkWithReadRepairTest}}
Coordinator-level exception:
{{java.lang.AssertionError: Error merging RTs on ks1.tbl:}}
