Work Description: zabetak commented on pull request #2432:
URL: https://github.com/apache/hive/pull/2432#issuecomment-951762656
> So, what would the affect be if the time were to pass and another write
request came in? Would it create a second file? Append to the end of an
existing file? Is the original log files always deleted when the logger goes
idle?
The deletion of the log files is not handled by Log4j (not in this case at
least). When the logger goes idle, the appender is closed along with the
respective file descriptor but the file remains as is. When the appender comes
back it will write to the same file; if for whatever reason the file is not
there it will create a file with the same name and start writing there.
