Whether the Live Loader can ignore this record when it reports an error and let it continue

Hi @gumupaier, sorry there is no such provision to ignore errors in the live loader. However, bulk loader does provide that kind of ignoring of errors (check --ignore_errors flag).

Also, can you please open up an issue on https://github.com/dgraph-io/dgraph/issues for the feature request. This would help team track the issue, discuss it and address it properly.
