has experienced same issue or happens know how means?

thank much, juan m. sierra

i had error, , problem had defined "id space" in 1 of node header files.

i needed use id spaces because node identifiers not unique across node files (my nodes had sequential identifiers), used cool feature called id space: http://neo4j.com/docs/2.2.6/import-tool-header-format.html#_id_spaces

here example shows syntax id spaces: http://neo4j.com/docs/stable/import-tool-id-handling.html

in summary: if use id spaces, of nodes must have own id spaces. otherwise error "mixing specified , unspecified group belongings in single import".
