解决思路:
1.分析这句话,
17/03/02 21:01:56 WARN net.ScriptBasedMapping: Exception running /etc/spark2/conf.cloudera.spark2_on_yarn/yarn-conf/topology.py 172.16.102.64
java.io.IOException: Cannot run program "/etc/spark2/conf.cloudera.spark2_on_yarn/yarn-conf/topology.py" (in directory "/yarn/nm/usercache/spark/appcache/application_1488459089260_0003/container_1488459089260_0003_01_000001"): error=2, No such file or directory
说明在这个ip的机器上 没有这个py文件。
然后去机器验证，
然后再将01机器的 配置文件 全部copy到另外四台即可。
scp -r /etc/spark2/conf.cloudera.spark2_on_yarn root@hadoop-02:/etc/spark2/
scp -r /etc/spark2/conf.cloudera.spark2_on_yarn root@hadoop-03:/etc/spark2/
scp -r /etc/spark2/conf.cloudera.spark2_on_yarn root@hadoop-04:/etc/spark2/
scp -r /etc/spark2/conf.cloudera.spark2_on_yarn root@hadoop-05:/etc/spark2/
验证:
就ok了
