"hadoop fs -text" does not give a useful text representation of MapWritable objects -----------------------------------------------------------------------------------
Key: HADOOP-6842 URL: https://issues.apache.org/jira/browse/HADOOP-6842 Project: Hadoop Common Issue Type: Improvement Affects Versions: 0.20.0 Reporter: Steven Wong If a sequence file contains MapWritable objects, running "hadoop fs -text" on the file prints the following for each MapWritable: org.apache.hadoop.io.mapwrita...@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(); } -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
