用Maxine运行伏地魔的UnsatisfiedLinkError

Question

我试图使用maxine在Voldemort上运行一个节点集群，并遇到了这个问题。似乎和南航有关？你能帮帮我吗？

下面是我使用的命令：

  ./maxine/com.oracle.max.vm.native/generated/linux/maxvm -cp .voldemort/voldemort-release-1.9.0-cutoff/dist/voldemort-1.9.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/dist/voldemort-1.9.0-src.jar:.voldemort/voldemort-release-1.9.0-cutoff/dist/voldemort-contrib-1.9.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/dist/voldemort-test-1.9.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/avro-1.4.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/azkaban-common-0.05.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/catalina-ant.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/colt-1.2.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-codec-1.4.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-collections-3.2.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-configuration-1.6.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-dbcp-1.2.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-io-1.4.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-lang-2.4.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-logging-1.1.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/commons-pool-1.5.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/compress-lzf-0.9.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/data-1.15.18.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/gson-2.2.4.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/guava-14.0.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/hadoop-auth-2.0.5-alpha.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/hadoop-core-1.0.4.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/httpclient-4.1.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/httpcore-4.1.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jackson-core-asl-1.4.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jackson-mapper-asl-1.4.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jdom-1.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/je-5.0.88.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jetty-6.1.18.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jetty-util-6.1.18.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jline-0.9.94.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jna.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/joda-time-1.6.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/jopt-simple-4.6.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/junit-4.6.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/krati-0.3.6.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/libthrift-0.5.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/log4j-1.2.15.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/mail-1.4.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/mockito-all-1.8.5.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/netty-3.5.8.Final.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/paranamer-2.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/pegasus-common-1.15.18.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/protobuf-java-2.3.0.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/r2-1.15.18.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/scala-compiler-2.10.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/scala-library-2.10.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/scala-reflect-2.10.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/servlet-api-2.5.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/slf4j-api-1.5.6.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/slf4j-log4j12-1.5.6.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/snappy-0.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/tehuti-0.5.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/tusk-0.0.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/typica-1.7.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/velocity-1.6.2.jar:.voldemort/voldemort-release-1.9.0-cutoff/lib/xercesImpl-2.9.1.jar:.voldemort/voldemort-release-1.9.0-cutoff/contrib/*/lib/*.jar:.voldemort/voldemort-release-1.9.0-cutoff/dist/resources -Dlog4j.configuration=file://.voldemort/voldemort-release-1.9.0-cutoff/src/java/log4j.properties -Xmx2G -server -Dcom.sun.management.jmxremote voldemort.server.VoldemortServer config/single_node_cluster/

我获得的错误输出：

谢谢!

Answer 1

这个问题与Maxine中缺少sun.misc.Unsafe.getLoadAverage方法的实现有关。

提交https://github.com/beehive-lab/Maxine-VM/commit/9f36e8a1d9fa54d74b8bfa3f632814a7be9e2ae2解决了这个问题，直到提供了一个实际的实现。
