Review request for Sqoop.


Changes
-------

Here's a version that looks for mkfifo and falls back to mknod if it's not 
available. This should gracefully handle any os without introducing a new 
configuration parameter.


Summary
-------

Replaced the use of mknod with mkfifo in NamedFifo to improve compatibility 
with Mac OS X.


This addresses bug SQOOP-339.
    https://issues.apache.org/jira/browse/SQOOP-339


Diffs (updated)
-----

  src/java/com/cloudera/sqoop/io/NamedFifo.java 38656cb 

Diff: https://reviews.apache.org/r/1938/diff


Testing
-------

No new tests as the functionality is covered by an existing unit test. I ran 
the existing unit test and it worked. I don't have a Mac to test on right now, 
so it might be good to run the unit tests on one before commit.


Thanks,

Joey

> Duplicating this issue from SQOOP-175, which is in the cloudera JIRA
> From SQOOP-175's description by Ken Krugler :
> On Mac OS X 10.6.3, the TestNamedFifo.testNamedFifo() test fails. The error 
> is caused by the Shell.execCommand() use of mknod, since (at least on my Mac) 
> mknod doesn't know about the --mode=xxx parameter or the -p parameters.
> Based on 
> http://stackoverflow.com/questions/4546356/is-mknod-portable-if-not-what-is-the-alternative,
>  I switched the code to use mkfifo and it now passes all tests.
> The change to NamedFifo.create() is trivial:
> Shell.execCommand("mkfifo", "-m", "0" + modeStr, filename);
> But I have no way of trying this out on other OSes, so it might create a 
> different compatibility issue.
