Key: HADOOP-10440
URL: https://issues.apache.org/jira/browse/HADOOP-10440
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.3.0

Reporter: guodongdong
In the HarFsInputStream of HarFileSystem, when reading data by interface "int
read(byte[] b)", "int read(byte[] b, int offset, int len)" wille be called and
position wille be update, so position need not be update in interface "int
read(byte[] b)"
public synchronized int read(byte[] b) throws IOException {
int ret = read(b, 0, b.length);
if (ret != -1) {
position += ret;
}
return ret;
}
/**

*/
public synchronized int read(byte[] b, int offset, int len)
throws IOException {
int newlen = len;
int ret = -1;
if (position + len > end) {
newlen = (int) (end - position);
}
// end case
if (newlen == 0)
return ret;
ret = underLyingStream.read(b, offset, newlen);
position += ret;
return ret;
}
