> Key: HADOOP-6842
> URL: https://issues.apache.org/jira/browse/HADOOP-6842
> Project: Hadoop Common
> Issue Type: Improvement
> Components: io
> Affects Versions: 0.20.0
> Reporter: Steven Wong
> Assignee: Akira AJISAKA
> Fix For: 3.0.0, 2.8.0
>
> Attachments: HADOOP-6842.002.patch, HADOOP-6842.patch
>
>
> If a sequence file contains MapWritable objects, running "hadoop fs -text" on
> the file prints the following for each MapWritable:
> org.apache.hadoop.io.MapWritable@4f8235ed
> To be more useful, it should print out the contents of the map instead. This
> can be done by adding a toString method to MapWritable, i.e. something like:
> public String toString() {
> return (new TreeMap<Writable, Writable>(instance)).toString();
> }
