| # The java implementation to use. Required. |

| # File naming remote slave hosts. $HADOOP_HOME/conf/slaves by default. |
| # export HADOOP_SLAVES=${HADOOP_HOME}/conf/slaves |

| # host:path where hadoop code should be rsync'd from. Unset by default. |

| # Seconds to sleep between slave commands. Unset by default. This |
| # can be useful in large clusters, where, e.g., slave rsyncs can |
| # otherwise arrive faster than the master can service them. |
