> IOUtils#skipFully hangs forever on EOF
> --------------------------------------
>
> Key: HADOOP-8614
> URL: https://issues.apache.org/jira/browse/HADOOP-8614
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 2.0.0-alpha
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Priority: Minor
> Attachments: HADOOP-8614.001.patch
>
>
> IOUtils#skipFully contains this code:
> {code}
> public static void skipFully(InputStream in, long len) throws IOException {
> while (len > 0) {
> long ret = in.skip(len);
> if (ret < 0) {
> throw new IOException( "Premature EOF from inputStream");
> }
> len -= ret;
> }
> }
> {code}
> The Java documentation is silent about what exactly skip is supposed to do in
> the event of EOF. However, I looked at both InputStream#skip and
> ByteArrayInputStream#skip, and they both simply return 0 on EOF (no
> exception). So it seems safe to assume that this is the standard Java way of
> doing things in an InputStream.
> Currently IOUtils#skipFully will loop forever if you ask it to skip past EOF!
