单独跑 NodeTest 试试

mvn --projects jraft-core test -Dtest=com.alipay.sofa.jraft.util. NodeTest#test*

这个问题 和平台 os 有关 我用ubuntu 16.04 跑 UT 没有问题

单独跑 NodeTest 试试

mvn --projects jraft-core test -Dtest=com.alipay.sofa.jraft.util. NodeTest#test*

Still failed。

@JerryYangSH Can you give more information? Which test case (method)？

@JerryYangSH Can you give more information? Which test case (method)？

It succeeds now after I cleaned /tmp and reboot the OS. It looks like something related to earlier unclean killed test process. I used the command "~/opensources/sofa-jraft$ mvn --projects jraft-core test -Dtest=com.alipay.sofa.jraft.core.NodeTest" . Thanks for your instant reply!
