Allen, thanks in advance!=20

The bulk loading from flatfile to htable one. =20
One thing I'm little confused is that the file path I supplied is to the
local path not the dfs, is this correct?
But when I tried to move the file to dfs and use the path there, it
gives me an error saying file cannot be found.

Hi Ding,

Caveat emptor, I'm also new to HBase and did those examples as part of
learning the API.  But I'll try to help you.

Which example are you using the flatfile -> HTable, or HTable -> HTable?
