Subject Hadoop update mysql table
Date Fri, 12 Apr 2013 05:43:39 GMT
Hi,all:

I'm trying to use Hadoop to read data, process and then write back to MySql. However, it seems
as if I can only do insertion. If I try to write back with the same primary key(it means update),
there will be an error like "Duplicate XXX for primary key'. Has anyone solved this problem?
And is it possible to update? Thanks very much!!!
