What is the default escape char

[ZongtianHou]

If I set the escape char to ‘\’, then after I insert (‘\\’,’abc’) into a table (a string, b string), on hdfs file the content is "\\",”abc"

But if I don’t set it, the content will become \abc, which will caused the \ be looked as escape and the two columns table became one column, I wonder what is the default escape character in hive, or in the hdfs content \abc.

Any info will be very appreciate, thank you very much!
