Review comment:
Instead of this, can we do the following in the constructor ?
```
if (fsDataInputStream.getWrappedStream() instanceof FSInputStream ) {
this.inputStream = new TimedFSDataInputStream(logFile.getPath(), new
FSDataInputStream(
new BufferedFSInputStream((FSInputStream)
fsDataInputStream.getWrappedStream(), bufferSize)));
} else if (**fsDataInputStream.getWrappedStream() instanceof
FSDataInputStream**) {
<initialize buffered input stream>
}
```
