> Can use java.lang.Throwable.addSuppressed(Throwable) instead of org.apache.hadoop.io.MultipleIOException
as 1.7+ java provides support for this. org.apache.hadoop.io.MultipleIOException can be deprecated
as for now
> {code}

> catch (IOException e) {
>           if(generalException == null)
>           {
>             generalException = new IOException("General exception");
>           }
>           generalException.addSuppressed(e);
>         }
> {code}
