> BulkLoader tool initializes schema unnecessarily via streaming

> Key: CASSANDRA-17740
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17740
> Project: Cassandra
> Issue Type: Bug
> Components: Tool/bulk load
> Reporter: Caleb Rackliffe

> Changes to streaming setup code for CASSANDRA-17663 mean that {{BulkLoader}}
> initializes the schema/system keyspace, which is not what we want in a tool.
> Initialization is due to a call to {{SystemKeyspace.getPreferredIP}} from the
> {{BulkLoader}} when it starts to transmit the SSTables from the bulk loader
> to the Cassandra instance.
> {noformat}
> getPreferredIP:1063, SystemKeyspace (org.apache.cassandra.db)
> sendMessage:213, StreamingMultiplexedChannel
> (org.apache.cassandra.streaming.async)
> sendControlMessage:191, StreamingMultiplexedChannel
> (org.apache.cassandra.streaming.async)
> sendControlMessage:1033, StreamSession (org.apache.cassandra.streaming)
> startStreamingFiles:1257, StreamSession (org.apache.cassandra.streaming)
> prepareSynAck:802, StreamSession (org.apache.cassandra.streaming)
> messageReceived:622, StreamSession (org.apache.cassandra.streaming)
> run:76, StreamDeserializingTask (org.apache.cassandra.streaming)
> run:30, FastThreadLocalRunnable (io.netty.util.concurrent)
> run:748, Thread (java.lang)
> {noformat}
> The existing {{BulkLoaderTest}} fails to detect this as it doesn't actually
> connect to anything so does not initialize streaming.
> Affects 4.1 and trunk, and may affect 4.0, although the 4.0 patch for
> CASSANDRA-17663 is different than 4.1+, and may require different mitigation.
