[jira] [Commented] (ARROW-3298) [C++] Move murmur3 hash implementation to arrow/util

    [ https://issues.apache.org/jira/browse/ARROW-3298?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16855725#comment-16855725 ] 

Antoine Pitrou commented on ARROW-3298:
---------------------------------------

What complicates things a bit is that there are several different versions of Murmur (murmur2, murmur3, 32-bit-hash-producing, 64-bit-hash-producing) and also potentially several different implementations of each (with different performance characteristics).

So some review of current usage accross the codebase (Arrow, Plasma, Parquet, Gandiva) is needed. [~fsaintjacques]

> It would be good to consolidate hashing utility code in a central place (this is currently in src/parquet)
