Are you talking about alignment restrictions (i.e. address must be a multiple of 8). Or something else? If it is something else, I would expect there to be a Sun/Oracle problem report open for this? > Unsafe.getLong is not supported correcly on Power PC, thus causing FastByteComparison's UnsafeComparer not working properly > --------------------------------------------------------------------------------------------------------------------------- > > Key: HADOOP-10843 > URL: https://issues.apache.org/jira/browse/HADOOP-10843 > Project: Hadoop Common > Issue Type: Bug > Components: io > Affects Versions: 2.2.0, 2.3.0, 2.4.0, 2.4.1 > Reporter: Jinghui Wang > Assignee: Jinghui Wang > Attachments: HADOOP-10843.patch > > > Unsafe.getLong is not supported correcly on Power PC.
