Subject [jira] [Commented] (HDFS-11110) Hardcoded BLOCK SIZE value of 4096 is not appropriate for PowerPC
Date Tue, 11 Jul 2017 18:40:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16082734#comment-16082734
] 

Bharat Viswanadham commented on HDFS-11110:
-------------------------------------------

In the test setup, the cacheManinpulator is set to NoMlockCacheManipulator.

 prevCacheManipulator = NativeIO.POSIX.getCacheManipulator();
    NativeIO.POSIX.setCacheManipulator(new NoMlockCacheManipulator());

So, here the NativeIO.java code also needs to be modified.

> Using NativeIO.POSIX.getCacheManipulator().getOperatingSystemPageSize() function rather
