[jira] [Updated] (HADOOP-10062)
TestMetricsSystemImpl#testMultiThreadedPublish fails on trunk
[ https://issues.apache.org/jira/browse/HADOOP-10062?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Shinichi Yamashita updated HADOOP-10062:
----------------------------------------
Attachment: HADOOP-10062.patch
I confirmed the change of the value in the test.
And I confirmed that there was the case which a order of the handling of MetricsSystemImpl#publishMetrics reversed.
This problem can be solved by synchronizing MetricsSystemImpl#publishMetricsNow.
I attach a patch file.
