Attachment: hadoop-7824.txt
How does something like this look?
Do we need to do the translation for the stat constants, too? Or are those standardized in POSIX?

-------------------------------------
Fix Version/s: 0.20.205.0
0.23.0
Status: Patch Available (was: Open)
This patch intended to demonstrate how what constants on OS X should look like. It breaks hadoop for systems other then OS X, so it is not intended to be used as is for the Hadoop project.

Colin Patrick McCabe commented on HADOOP-7824:
----------------------------------------------
I think we should just do the translation in the JNI code.
In general, people expect the jar files to be portable, meaning you can copy them from one PC to another without suffering disaster. This will not be true if we start injecting native constants into the Java code. In contrast, {{libhadoop.so}} is designed to contain the operating-system and architecture-specific parts of the code.
Also, do we really want to depend on Perl for our build process? I realize there's already a {{changes2html.pl}} script, but in general Perl seems like another build dependency we'd be better off without. Installing Perl on some platforms will definitely be a hassle-- like Windows. We also don't document our Perl dependency anywhere right now.
bq. I suspect that [translating the constants] is going to be a lot slower.
I seriously doubt that the performance difference between translating the constants and passing them straight through will even be measurable. If you like, I can do some before and after benchmarks with constant translation and without. Keep in mind, this is a couple of if statements every time we open a file. Considering the other performance issues we have to tackle, this is less than noise-- on par with changing constants because you believe comparisons with 0 are faster, etc.

I suspect that's going to be a lot slower. The C compiler should be able to optimize the heck out of pre-generated code rather than doing it on the fly. Given that the whole reason why this code exists is speed....

Summary: Native IO uses wrong constants almost everywhere (was: Native IO uses wrong constants on OS X)
Changing this to reflect reality. NativeIO.java's definitions mismatch RHEL 6 as well, which means that even on Linux this is untrustworthy.

Attachment: HADOOP-7824.patch
This patch generates a bit field translator based upon what Hadoop thinks is true in NativeIO.java vs. what fcntl.h and friends know is real.
This isn't fully cooked into the build process yet, however.

[jira] [Commented] (HADOOP-7824) Native IO uses wrong constants
almost everywhere
Posted by "Todd Lipcon (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-7824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13402763#comment-13402763 ]
Todd Lipcon commented on HADOOP-7824:
-------------------------------------
Instead of generating code at compile time like this, can we do better by creating enums on the Java side, and then translating from the Java enum to the C constants in the JNI layer? See how Errno.java translates to its C counterpart.
