wankunde commented on issue #546: [GRIFFIN-295]Limit the memory used by test case URL: https://github.com/apache/griffin/pull/546#issuecomment-548766442 Hi, @joohnnie First, as I described in this PR, the maven memory can be limited used by setting MAVEN_OPTS, which is required. But we also need to limit the spark jobs memory because JVM stores many unused objects before full GC occurs. SPARK project also sets this configuration . https://github.com/apache/spark/blob/14337f68e328c3faad81d3051a56be080a31509d/pom.xml#L2329 https://github.com/apache/spark/blob/14337f68e328c3faad81d3051a56be080a31509d/pom.xml#L2379 Second, there was a `No output has been received in the last 10m0s` error, and I don't know what's wrong with the travis build container, so printing more log message helps troubleshoot. https://travis-ci.org/apache/griffin/builds/605545271?utm_medium=notification&utm_source=github_status ``` No output has been received in the last 10m0s, this potentially indicates a stalled build or something wrong with the build itself. Check the details on how to adjust your build configuration on: https://docs.travis-ci.com/user/common-build-problems/#build-times-out-because-no-output-was-received The build has been terminated ``` What do you think, @joohnnie
