Hello Impala Public Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/16414 to look at the new patch set (#2). Change subject: WIP IMPALA-9046: Profile counter that indicates if a JVM pause occurred ...................................................................... WIP IMPALA-9046: Profile counter that indicates if a JVM pause occurred Adds a new section to the host profiles that includes JVM GC related metrics. These metrics are taken from JMX and the JvmPauseMonitor. The host profiles will now include a section like below: JVM: - GcCount: 19 - GcNumInfoThresholdExceeded: 0 - GcNumWarnThresholdExceeded: 0 - GcTimeMillis: 17s476ms - GcTotalExtraSleepTimeMillis: 380 GcNumInfoThresholdExceeded, GcNumWarnThresholdExceeded, and GcTotalExtraSleepTimeMillis are all taken from JvmPauseMonitor. GcCount and GcTimeMillis are taken from JMX (specifically, GarbageCollectorMXBean). The counters themselves are derived from the impalad host-level metrics. Testing: * Added a test that runs Java UDF, which triggers JVM GC TODO: * Run core tests * Considering re-working JvmMetricCache::lock_ usage to reduce potential lock contention Change-Id: Idbaae2f9142b8be94532a0a147668a3d96091b0b --- M be/src/runtime/query-state.cc M be/src/util/memory-metrics.cc M be/src/util/memory-metrics.h A tests/custom_cluster/test_observability.py A tests/test-hive-udfs/src/main/java/org/apache/impala/JavaGcUdfTest.java 5 files changed, 185 insertions(+), 17 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/14/16414/2 -- To view, visit http://gerrit.cloudera.org:8080/16414 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newpatchset Gerrit-Change-Id: Idbaae2f9142b8be94532a0a147668a3d96091b0b Gerrit-Change-Number: 16414 Gerrit-PatchSet: 2 Gerrit-Owner: Sahil Takiar <stak...@cloudera.com> Gerrit-Reviewer: Impala Public Jenkins <impala-public-jenk...@cloudera.com>
