             Summary: Investigate Why TestBsonRecordReader needs 900kb to run
                 Key: DRILL-6352
                 URL: https://issues.apache.org/jira/browse/DRILL-6352
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Timothy Farkas


TestBsonRecordReader requires 400kb on the allocator in order to run all tests successfully. This seems like it too much. Reducing the memory below that to 300kb will cause an IOB

objc[92518]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/bin/java (0x10e8fe4c0) and /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre/lib/libinstrument.dylib (0x10e9824e0). One of the two will be used. Which one is undefined.
