数据没有生成相关问题

[ergouy]

个人感觉可能hadoop-streaming-3.2.2.jar有问题(我没有去看这个jar包的代码)，因为全程没报错，但是表里就是没数据，我定位后发现，dbgen.sh这个脚本没有被执行(因为我在这个脚本中设置的输出并没有输出)。

Hi, @ergouy Would you mind rewriting your contents with English? It would be readable for English speakers. I met the same issue as yours on Hadoop 3.2.1. I checked the stderr of the mapreduce job dbgen and found an error in it:

/path/to/dbgen.sh: line 32: hadoop: command not found

I'm not quite sure about the root cause. I try to add the environment variables for Hadoop in dbgen.sh and then it works. The data is generated correctly. Therefore, I think maybe you could try my solution.

export HADOOP_HOME='/usr/lib/hadoop-current'
export PATH=$PATH:$HADOOP_HOME/bin
