Branimir Lambov resolved CASSANDRA-7466.
----------------------------------------
Resolution: Not A Problem
> Unit Test Suite Breaks when Run in a Single JVM
> -----------------------------------------------
>
> Key: CASSANDRA-7466
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7466
> Project: Cassandra
> Issue Type: Bug
> Components: Testing
> Environment: MacOS 10.9.3, IntelliJ IDEA 14, Java 1.8.0_65
> Reporter: Caleb William Rackliffe
> Assignee: Caleb William Rackliffe
> Priority: Minor
> Labels: unit-test
>
> I pulled down the source and followed
> http://wiki.apache.org/cassandra/RunningCassandraInIDEA to import C* as an
> IDEA project. Everything in the tutorial works as it should, but when I tried
> to run the unit tests in {{test/unit/org.apache.cassandra}}, the suite fails
> a few tests in, complaining variously about a hodgepodge of things like:
> {noformat}
> FSWriteError in
> build/test/cassandra/data/cql_test_keyspace/table_1-0fd6a7109a1311e586ed079249e818e0/backups/cql_test_keyspace-table_1.some_index-ka-5-Summary.db
