I want to install Spark Standlone mode to a Cluster with my two virtual machines.
With the version of spark-0.9.1-bin-hadoop1, I execute spark-shell successfully in each vm. I follow the offical document to make one vm(ip:xx.xx.xx.223) as both Master and Worker and to make the other(ip:xx.xx.xx.224) as Worker only.
But the 224-ip vm cannot connect the 223-ip vm. Followed is 223(Master)'s master log: 

[@tc-52-223 logs]# tail -100f spark-root-org.apache.spark.deploy.master.Master-1-tc-52-223.out

Followed is my spark-env.sh:

JAVA_HOME=/usr/local/jdk
export SPARK_MASTER_IP=tc-52-223
export SPARK_WORKER_CORES=1
export SPARK_WORKER_INSTANCES=1
export SPARK_MASTER_PORT=7077
export SPARK_WORKER_MEMORY=4g
export MASTER=spark://${SPARK_MASTER_IP}:${SPARK_MASTER_PORT}
export SPARK_LOCAL_IP=tc-52-223

I have googled many solutions, but they cant work. Please help me.

I'm not sure if this is the same issue I encountered but you may want to try setting SPARK_MASTER_IP the same as what spark binds to. In your example is looks like it would be 10.11.52.223 and not tc-52-223.

It should be the same as what you see when you visit the master node web UI on 8080. Something like: Spark Master at spark://ec2-XX-XX-XXX-XXX.compute-1.amazonaws.com:7077
