Ted Yu created HBASE-21097: ------------------------------ Summary: Flush pressure assertion may fail in testFlushThroughputTuning Key: HBASE-21097 URL: https://issues.apache.org/jira/browse/HBASE-21097 Project: HBase Issue Type: Test Reporter: Ted Yu
>From >https://builds.apache.org/job/PreCommit-HBASE-Build/14137/artifact/patchprocess/patch-unit-hbase-server.txt > : {code} [ERROR] testFlushThroughputTuning(org.apache.hadoop.hbase.regionserver.throttle.TestFlushWithThroughputController) Time elapsed: 17.446 s <<< FAILURE! java.lang.AssertionError: expected:<0.0> but was:<1.2906294173808417E-6> at org.apache.hadoop.hbase.regionserver.throttle.TestFlushWithThroughputController.testFlushThroughputTuning(TestFlushWithThroughputController.java:185) {code} Here is the related assertion: {code} assertEquals(0.0, regionServer.getFlushPressure(), EPSILON); {code} where EPSILON = 1E-6 In the above case, due to margin of 2.9E-7, the assertion didn't pass. It seems the epsilon can be adjusted to accommodate different workload / hardware combination. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
