> Running all the tests under TestMiniTezCliDriver very frequently (but still intermittently) leads to OutOfMemory errors.
> {noformat}
> cd itests/qtest && mvn test -Dtest=TestMiniTezCliDriver
> {noformat}
> I set {{-XX:+HeapDumpOnOutOfMemoryError}} and the respective heapdumps are attached to this ticket.
> The OOM is thrown from the application master and a quick inspection of the dumps shows that it comes mainly from the accumulation of Configuration objects (~1MB each) by various classes.
> The max heap size for application master is pretty low (~100MB) so it is quite easy to reach. The heap size is explicitly very low for testing purposes but maybe we should re-evaluate the current configurations for the tests.
