启动spark报错

启动spark报错如下：
[hadoop@yun01-nn-01 sbin]$ ./start-all.sh
starting org.apache.spark.deploy.master.Master, logging to /application/hadoop/spark/sbin/../logs/spark-hadoop-org.apache.spark.deploy.master.Master-1-yun01-nn-01.out
failed to launch org.apache.spark.deploy.master.Master:
  Failed to find Spark assembly in /application/hadoop/spark/assembly/target/scala-2.10
  You need to build Spark before running this program.


原来是版本不对应。
