Zheng Shao commented on HIVE-136:
---------------------------------
In HIVE-270 I put a link to how MySQL does escaping. That seems to be a clean
solution although it won't support string.split or even splitting lines using
"\n".
If we change "\005" with "\\" in your case, it won't work with the symmetric
escaping/unescaping logic as well.
What about this? We explicitly allow users to enable/disable escaping. If the
user disable it, then we just do nothing (and the data may look corrupt to them
- but that's the only thing we can do). If the user enable it, then we do the
escaping/unescaping logic as I mentioned (not symmetric, but try to guess what
the user really means).
