Hudson commented on HADOOP-6842: -------------------------------- SUCCESS: Integrated in Hadoop-Yarn-trunk-Java8 #191 (See [https://builds.apache.org/job/Hadoop-Yarn-trunk-Java8/191/]) HADOOP-6842. "hadoop fs -text" does not give a useful text representation of MapWritable objects (evans: rev cc17c83585f581d56e7c42b91464cd7a99e8cf90) * hadoop-common-project/hadoop-common/CHANGES.txt * hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/io/TestMapWritable.java * hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/io/MapWritable.java > "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 > 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(); > } -- This message was sent by Atlassian JIRA (v6.3.4#6332)
