> Key: CASSANDRA-21470

> Project: Apache Cassandra
> Issue Type: Bug
> Components: Consistency/Coordination

> Priority: Normal
> Time Spent: 20m
> Remaining Estimate: 0h
>
> To determine which SSTables to stream for bulk import, we filter based off of
> the interval tree we construct with shard ranges. However, it is possible
> that there are false positives. An example would be with a shard range of
> [3,8] and a SSTable containing two elements 1 and 9 with a range of [1,9]. In
> this case, when we compute the SSTable sections, we end up not streaming any
> SSTables. This causes exceptions to be thrown in the bulk import path.
