Spark - Add Worker from Local Machine (standalone spark cluster manager)?

Question

When running spark 1.4.0 in a single machine, I can add worker by using this command "./bin/spark-class org.apache.spark.deploy.worker.Worker myhostname:7077". The official documentation points out another way by adding "myhostname:7077" to the "conf/slaves" file followed by executing the command "sbin/start-all.sh" which invoke the master and all workers listed in conf/slaves file. However, the later method doesn't work for me (with time-out error). Can anyone help me with this?

Here is my conf/slaves file (assume the master URL is myhostname:700):

myhostname:700

Answer 1

conf.slaves文件应该只是主机名列表，您不需要包括spark所在的端口号（我认为如果这样做，它将尝试在该端口上使用ssh，这可能是超时的来源） ）。
