我有一个在 VM 上运行的 cloudera cdh5.3 快速入门。我在运行 Spark 时遇到问题。我已经完成了这些步骤http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/cdh_ig_spark_configure .... 并运行单词 exapmle 并且它起作用了。但是当我去master（quickstart.cloudera：18080）时，那里没有工人，核心= 0，内存= 0 ...当我去（quickstart.cloudera：18081）时，那里有工人。我的问题是如何添加工人？我应该在导出 STANDALONE_SPARK_MASTER_HOST 中输入什么？
这是 spark-env.sh：
#Change the following to specify a real cluster's Master host
export STANDALONE_SPARK_MASTER_HOST=worker-20150402201049-10.0.2.15-7078
export SPARK_MASTER_IP=$STANDALONE_SPARK_MASTER_HOST
### Let's run everything with JVM runtime, instead of Scala
export SPARK_LAUNCH_WITH_SCALA=0
export SPARK_LIBRARY_PATH=${SPARK_HOME}/lib
export SCALA_LIBRARY_PATH=${SPARK_HOME}/lib
export SPARK_MASTER_WEBUI_PORT=18080
export SPARK_MASTER_PORT=7077
export SPARK_WORKER_PORT=7078
export SPARK_WORKER_WEBUI_PORT=18081
export SPARK_WORKER_DIR=/var/run/spark/work
export SPARK_LOG_DIR=/var/log/spark
export SPARK_PID_DIR='/var/run/spark/'
if [ -n "$HADOOP_HOME" ]; then
export LD_LIBRARY_PATH=:/lib/native
fi
export HADOOP_CONF_DIR=${HADOOP_CONF_DIR:-etc/hadoop/conf}
### Comment above 2 lines and uncomment the following if
### you want to run with scala version, that is included with the package
#export SCALA_HOME=${SCALA_HOME:-/usr/lib/spark/scala}
#export PATH=$PATH:$SCALA_HOME/bin
谢谢
