> Looking at recent night test runs (testing.confluent.io/kafka), the storage requirements for log output from the various services has increased significantly, up to 7-10G for a single test run, up from hundreds of MB
> Current breakdown:
> 23M	Benchmark
> 3.2M	ClientCompatibilityTest
> 613M	ConnectDistributedTest
> 1.1M	ConnectRestApiTest
> 1.5M	ConnectStandaloneFileTest
> 2.0M	ConsoleConsumerTest
> 440K	KafkaVersionTest
> 744K	Log4jAppenderTest
> 49M 	QuotaTest
> 3.0G	        ReplicationTest
> 1.2G	        TestMirrorMakerService
> 185M	TestUpgrade
> 372K	TestVerifiableProducer
> 2.3G	        VerifiableConsumerTest
> The biggest contributors in these test suites:
> ReplicationTest:
> verifiable_producer.log (currently TRACE level)
> VerifiableConsumerTest:
> kafka server.log
> TestMirrorMakerService:
> verifiable_producer.log
> ConnectDistributedTest:
> kafka server.log
> The worst offenders are therefore 
> verifiable_producer.log which is logging at TRACE level, and kafka server.log which is logging at debug level
> One solution is to:
> 1) Update the log4j configs to log separately to both an INFO level file, and another file for DEBUG at least for the worst offenders.
> 2) Don't collect these DEBUG (and below) logs by default; only mark for collection during failure
