Ayappan updated HADOOP-11462:
-----------------------------
Attachment: HADOOP-9627-v2.patch
> TestSocketIOWithTimeout needs change for PowerPC platform
> ---------------------------------------------------------
>
> Key: HADOOP-11462
> URL: https://issues.apache.org/jira/browse/HADOOP-11462
> Project: Hadoop Common
> Issue Type: Bug
> Components: test
> Affects Versions: 2.5.2
> Environment: PowerPC
> Reporter: Ayappan
> Assignee: Ayappan
> Attachments: HADOOP-9627-v1.patch, HADOOP-9627-v2.patch

> TestSocketIOWithTimeout uses a block size of 4192 bytes to simulate a partial
> write. This seems to be a valid in x86 architecture where the default minimum
> blocksize is 4096.
> This testcase fails in PowerPC where the default minimum block size is 65536
> bytes (64KB). So for PowerPC, using a blocksize little more than 64K , say
> 65555(65536 + 19) holds good for this scenario.
> I attached a patch here where i made it very general by introducing
> NativeIO.POSIX.getCacheManipulator().getOperatingSystemPageSize() to get the
> page size.
> I tested my patch in both ppc64 and x86 linux machines.
