    Description

      Running all the tests under TestMiniTezCliDriver very frequently (but still intermittently) leads to OutOfMemory errors.

      cd itests/qtest && mvn test -Dtest=TestMiniTezCliDriver

      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.
