- need cherry-pick terror to master

[csuzhangxc]

NOTE: should this terror also be added in master, to avoid future conflict?

YES. all errors in all branches should always be the same, and in fact, before releasing any version, we must ensure errros codes have synced between branches.

BTW, does the master branch (with the newest dumpling) has this problem?

BTW, does the master branch (with the newest dumpling) has this problem?

if this fail is caused by lack of RELOAD privilege, dumpling could keep pause.

"Error 1227: Access denied; you need (at least one of) the RELOAD privilege(s) for this operation"

but we can't simulate other fail reason

OK, we can only fix it in release-1.0 now.
