[jira] [Updated] (GIRAPH-530) GiraphInputFormat#getSplits() should be aware of multithreaded input

["Alessandro Presta (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GIRAPH-530?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alessandro Presta updated GIRAPH-530:
-------------------------------------

    Attachment: GIRAPH-530.patch

- Changes the semantics of the second argument from "number of workers" to "minimum number of splits".
- Relevant callers now pass the total number of input threads instead of just workers.

> The current signature of getSplits() assumes that the only piece of information needed in order to determine the number of splits is the number of workers.
> With multiple input threads for each worker, this is no longer the case.
> We could solve this very simply by renaming the numWorkers parameter to something like minSplitCountHint, and changing any existing callers to pass the total number of input threads instead of workers.
