Aaron Fabbri created HADOOP-15040: ------------------------------------- Summary: AWS SDK NPE bug spams logs w/ Yarn Log Aggregation Key: HADOOP-15040 URL: https://issues.apache.org/jira/browse/HADOOP-15040 Project: Hadoop Common Issue Type: Bug Components: fs/s3 Affects Versions: 3.0.0-beta1 Reporter: Aaron Fabbri Assignee: Aaron Fabbri
My colleagues working with Yarn log aggregation found that they were getting this message spammed in their logs when they used an s3a:// URI for logs (yarn.nodemanager.remote-app-log-dir): {noformat} getting attribute Region of com.amazonaws.management:type=AwsSdkMetrics threw an exception javax.management.RuntimeMBeanException: java.lang.NullPointerException at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.rethrow(DefaultMBeanServerInterceptor.java:839) at <snip> Caused by: java.lang.NullPointerException at com.amazonaws.metrics.AwsSdkMetrics.getRegion(AwsSdkMetrics.java:729) at com.amazonaws.metrics.MetricAdmin.getRegion(MetricAdmin.java:67) at sun.reflect.GeneratedMethodAccessor132.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at sun.reflect.misc.Trampoline.invoke(MethodUtil.java:71) at sun.reflect.GeneratedMethodAccessor12.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) {noformat} This happens even though the aws sdk cloudwatch metrics reporting was disabled (default), which is a bug. I filed a [github issue|https://github.com/aws/aws-sdk-java/issues/1375|] and it looks like a fix should be coming around SDK release 1.11.229 or so. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
