Sanjay Radia commented on HDFS-4260:
------------------------------------
There is a better way to fix this. See HADOOP-8487.
TEST_ROOT_DIR is set to the build dir. This is fine for local tests.
For HDFS tests this just happens to work for unix platforms because we could
create the same build dir path on HDFS. For windows this fails since the build
dir is "C:/.....".
HDFS-8487 fixed this for FileSystem tests as follows:
* it made the TEST_ROOT_DIR non-final
* individual HDFS tests set the TEST_ROOT_DIR to be something like
/tmp/TestName.
Such a patch can be applied directly to trunk and merged to the windows branch.
