Colin Patrick McCabe commented on HDFS-6288:
--------------------------------------------
Oops, there is a test failure that needs to be addressed. The test failure in
{{TestPread}} is because of this new addition:
{code}
private void doPread(FSDataInputStream stm, long position, byte[] buffer,
int offset, int length) throws IOException {
int nread = 0;
if (!(stm.getWrappedStream() instanceof DFSInputStream)) {
throw new IOException("not DFSInputStream");
}
...
{code}
We need to support non-{{DFSInputStream}} objects here so that we can test
{{LocalFS}} and so forth.
