> Now the error log is too simple and cannot provide enough info for debugging. And this error will failed the write operation and finally lead our critical tasks failed. It will be good to print retry time and file path info in {{DFSOutputStream#completeFile}}. In addition, the log level can be updated from INFO to WARN, it won't be ignored easily by users.
