Matt Foley commented on HADOOP-7326:
------------------------------------
In HADOOP-7284, Todd observes that TestTrash is "supposed to set up a
LocalFileSystem subclass (TestLFS) that responded with a directory inside
build/ as a home dir". Seems like that would be a good way to get around this
silliness with shared .Trash directory. It looks like the current
implementation is deficient. I'll look into fixing it.

> This bug was discovered while investigating HDFS-1967, intermittent failure
> of TestHDFSTrash, which calls TestTrash. If the user id running the test has
> a ~/.Trash directory that already has 4 or more files in it, a loop in
> TestTrash.testTrashEmptier() will never terminate, because it is waiting for
> the count of objects to increase from zero to exactly three (and it creates
> one object right away).
