> 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 inĀ {{DFSOutputStream#completeFile}}. In addition,
the log level can be updated from INFO to WARN, it won't be ignored easily by users.
