Ayappan created HADOOP-11462: -------------------------------- Summary: TestSocketIOTimeout 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
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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
