[jira] [Issue Comment Deleted] (HADOOP-11505) Various native parts
use bswap incorrectly and unportably
[ https://issues.apache.org/jira/browse/HADOOP-11505?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Chris Nauroth updated HADOOP-11505:
-----------------------------------
Comment: was deleted
(was: hadoop-hdfs-native-client does build with CMake on Windows. The native container executor in hadoop-yarn-server-nodemanager does not build at all on Windows. hadoop-common uses a checked-in Visual Studio solution file to handle the Windows build. There is a JIRA somewhere to track converting to CMake for Windows in hadoop-common. Meanwhile, a short-term fix is probably to check in some kind of hand-crafted version like you said.)

> hadoop-mapreduce-client-nativetask fails to use x86 optimizations in some cases. Also, on some alternate, non-x86, non-ARM architectures the generated code is incorrect. Thanks to Steve Loughran and Edward Nevill for finding this.
