eclipse调试yarn

按上一篇文章无错误eclipse导入hadoop源码后
到hadoop发行版的etc/hadoop里在yarn-env.sh里
加上

export YARN_RESOURCEMANAGER_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9999"export YARN_NODEMANAGER_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9998"

注意不能有错字母，似乎单词顺序也不能错，否则FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)
