Description

org.apache.hadoop.io.nativeio.TestNativeIO#testPosixFadvise() failed on Windows. Here is the error information.
\dev\zero (The system cannot find the path specified)
java.io.FileNotFoundException: \dev\zero (The system cannot find the path specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:120)
at java.io.FileInputStream.<init>(FileInputStream.java:79)
at org.apache.hadoop.io.nativeio.TestNativeIO.testPosixFadvise(TestNativeIO.java:277)
The root cause of this is "/dev/zero" is used and Windows does not have devices like the unix /dev/zero or /dev/random.
