Steve Loughran commented on HADOOP-15446: ----------------------------------------- +1, committed to branch 3.1 & trunk. If you want backporting to branch-2, run the tests, tell me how it went, & I'll backport. I did see one failure in my own test run, I'm assuming unrelated and just a function of network distance. {code} [ERROR] Tests run: 5, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 26.213 s <<< FAILURE! - in org.apache.hadoop.fs.azure.TestClientThrottlingAnalyzer [ERROR] testManySuccessAndErrorsAndWaiting(org.apache.hadoop.fs.azure.TestClientThrottlingAnalyzer) Time elapsed: 1.123 s <<< FAILURE! java.lang.AssertionError: The actual value 9 is not within the expected range: [5.60, 8.40]. at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.assertTrue(Assert.java:41) at org.apache.hadoop.fs.azure.TestClientThrottlingAnalyzer.fuzzyValidate(TestClientThrottlingAnalyzer.java:46) at org.apache.hadoop.fs.azure.TestClientThrottlingAnalyzer.testManySuccessAndErrorsAndWaiting(TestClientThrottlingAnalyzer.java:168) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:47) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:44) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.RunBefores.evaluate(RunBefores.java:26) at org.junit.rules.TestWatcher$1.evaluate(TestWatcher.java:55) at org.junit.internal.runners.statements.FailOnTimeout$StatementThread.run(FailOnTimeout.java:74) {code} > WASB: PageBlobInputStream.skip breaks HBASE replication > ------------------------------------------------------- > > Key: HADOOP-15446 > URL: https://issues.apache.org/jira/browse/HADOOP-15446 > Project: Hadoop Common > Issue Type: Bug > Components: fs/azure > Affects Versions: 2.9.0, 3.0.2 > Reporter: Thomas Marquardt > Assignee: Thomas Marquardt > Priority: Major > Attachments: HADOOP-15446-001.patch, HADOOP-15446-002.patch, > HADOOP-15446-003.patch > > > Page Blobs are primarily used by HBASE. HBASE replication, which apparently > has not been used with WASB until recently, performs non-sequential reads on > log files using PageBlobInputStream. There are bugs in this stream > implementation which prevent skip and seek from working properly, and > eventually the stream state becomes corrupt and unusable. > I believe this bug affects all releases of WASB/HADOOP. It appears to be a > day-0 bug in PageBlobInputStream. There were similar bugs opened in the past > (HADOOP-15042) but the issue was not properly fixed, and no test coverage was > added. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
