# [DRILL-8268](https://issues.apache.org/jira/browse/DRILL-8268): Fix Hadoop 2 and Netty lib exclusions, REST mem limiter disabled by default ## Description New exclusions of slf4j-reload4j are required in the Hadoop 2 profile, probably due to the upgrade of Hadoop from 2.10.1 to 2.10.2. The netty-all metapackage entered the dependency tree with the change introducing the Netty bom bringing many uneeded libs with it. The heap memory usage limiting logic in the REST server is disabled by default since query results are streamed. This change aims to let the Java GC to now do its job without interference and if that results in OOM under a constant load then there is good evidence for a heap leak which must be tracked and completely resolved anyway, not mitigated or "swept under a rug". ## Documentation N/A ## Testing Lib exclusions: successful build and launch under the Hadoop 2 profile Heap memory usage: new (or existing) performance test in the drill-test-framework. -- This is an automated message from the Apache Git Service.
