Patch
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 .
