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.
> Hardcoded BLOCK SIZE value of 4096 is not appropriate for PowerPC
