Hadoop HDFS MapReduce输出到MongoDb错误

如何解决Hadoop HDFS MapReduce输出到MongoDb错误

我从网上学到了演示，并更改了一些细节，但出现错误 我有两台机器，一个主机和一个worker1，我在github中使用mongo-hadoop

文件：/ data / hadoop / tmp / attempt_local1130820149_0001_r_000000_0 / _MONGO_OUT_TEMP / _out，预期值：hdfs：//192.168.56.200：9000

我搜索了很多，其他人的错误对我来说是正确的

这是我的代码
