> The attached patch enables Hadoop to work on PPC64.
> That deals with SystemPageSize and BloclSize , which are not 4096 on PPC64.
> There are changes in 3 files:
> - hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/io/nativeio/NativeIO.java
> - hadoop-hdfs-project/hadoop-hdfs/src/test/java/org/apache/hadoop/hdfs/server/datanode/TestFsDatasetCache.java
> - hadoop-hdfs-project/hadoop-hdfs/src/test/java/org/apache/hadoop/hdfs/server/namenode/TestCacheDirectives.java
> where 4096 is replaced by getOperatingSystemPageSize() or by using PAGE_SIZE
> The patch has been built on branch-2.7 .
