Is the problem that the current build infrastructure rebuilds it even when nothing has changed? I've noticed that happening with other subcomponents. If that is the case then generating multiple, duplicate headers probably is both easier and quicker, although it sets my teeth slightly on edge. I can't comment about Yetus as I don't know anything about it. > Various native parts use bswap incorrectly and unportably > --------------------------------------------------------- > > Key: HADOOP-11505 > URL: https://issues.apache.org/jira/browse/HADOOP-11505 > Project: Hadoop Common > Issue Type: Bug > Affects Versions: 3.0.0 > Reporter: Colin Patrick McCabe > Assignee: Alan Burlison > Fix For: 3.0.0 > > Attachments: HADOOP-11505.001.patch, HADOOP-11505.003.patch, HADOOP-11505.004.patch, HADOOP-11505.005.patch, HADOOP-11505.006.patch, HADOOP-11505.007.patch > > > hadoop-mapreduce-client-nativetask fails to use x86 optimizations in some cases.
