Pentaho Kettle - 写入日志文件时出错

Question

We have a Pentaho job which is working fine in our local environment but we get an error writing to the log file after deploying it and running the job using Kettle. The error occurs in a job which has the setting 'Execute for every input row?' checked. Below is how the logging settings is configured the path and names are variables which are being set earlier. It is able to log to the file fine before this step.

Job Logging Configuration

This is error I get when running Kettle with log level of debug. Inside of the failing job we are also writing to the log which I don't know if that is a bad practice. Has anyone else come across this issue and know a resolution?

Answer 1

Read the log:

ProcessFiles - Could not write to "file://///QA/PentahoLogs/PartImportLog_20161005.txt" because it is currently in use.

so it means other process is locking the txt file.

确保日志路径/文件未被同一存储库用户或其他用户中的其他作业使用。
