Hi all, Is there a clean way to find out which worker a particular vertex is assigned to?
>From what I tried out, I found that given n workers, each node is assigned to >the worker with id (vertex_id % n ). Is that a safe way to do this? I’ve had a look at previous discussions, but most of them have no answer. ————————— Why I need it: In my application, each vertex needs to know some additional meta data, which is loaded from file. This metadata file is huge (>50 G) and so, on each worker, I only want to load the metadata corresponding to the vertices present on that worker. ————————— Previous discussions: 1. http://mail-archives.apache.org/mod_mbox/giraph-user/201310.mbox/%3C7EC16F82718A6D4A920A99FE46CE7F4E2861F779%40MERCMBX19R.na.SAS.com%3E 2. http://mail-archives.apache.org/mod_mbox/giraph-user/201403.mbox/%3CCAMf08QYE%2BRgUv9otXT6oPJorTNjQ-Ay8p4NUiuhds8%2BzgDzs1w%40mail.gmail.com%3E Regards, Kiran
