Andrey Klochkov commented on HDFS-4491:
---------------------------------------
Chris, as far as I can understand "trunk" doesn't support Windows currently.
Many tests fail and it doesn't seem there's an easy way to overcome this. I
noticed branch "branch-trunk-win" which seems to be dedicated to Windows
support - is it correct? Unfortunately I couldn't proceed too far with a
Windows VM and using this branch, as one of the requirements is MS Visual
Studio which I don't have.
Looking at the code in "trunk" I see that there are 14 tests using hardcoded
paths of the form "/tmp/<class name>". I'n not completely clear about the
reasons of this, can you please answer to clarify:
1. Why are these fixes applied to trunk while in general Windows support is
kept in "branch-trunk-win"?
2. Why are just a few tests fixed? There are many others which use
"test.build.data"
3. Is it a proper way to fix it? There are reasons of using "test.build.data"
to place all test data under. E.g. this data can be placed on ramfs to speedup
testing.
