      Description

      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 .
