[jira] [Commented] (HADOOP-11665) Provide and unify cross platform byteorder support in native code

    [ https://issues.apache.org/jira/browse/HADOOP-11665?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15013072#comment-15013072 ] 

Abhishek Soni commented on HADOOP-11665:
----------------------------------------

I have also checked that the endianness macro being used in the patch ('__BIG_ENDIAN__') is specifically defined by gcc on Mac. I have checked it for SLES Big Endian platform and it is not defined there. Therefore It doesn't seem to be reliable for platforms other than Mac.

I have modified the existing patch and used c code to check endianness instead of __BIG_ENDIAN__ macro.
I will be adding the modified patch (HADOOP-11665.002.patch) here. Please verify it.
