Detecting write mode (append, overwrite) in custom storage handler

[Julien Phalip <jp...@gmail.com>]

Hi,

I'm working on a custom storage handler and am wondering if there's a way
to detect the appropriate write mode for the output table. For example, an
"INSERT" statement is expected to append rows to the table, whereas an
"INSERT OVERWRITE" statement should first clear the table before adding new
rows.

Is there a way to tell which mode to use, either from the JobConf or any
other means?

Thanks,

Julien
