Doug Cutting commented on HADOOP-8597: -------------------------------------- This looks like a useful addition. Can you please add a unit test for it? > FsShell's Text command should be able to read avro data files > ------------------------------------------------------------- > > Key: HADOOP-8597 > URL: https://issues.apache.org/jira/browse/HADOOP-8597 > Project: Hadoop Common > Issue Type: New Feature > Components: fs > Affects Versions: 2.0.0-alpha > Reporter: Harsh J > Labels: newbie > Attachments: HADOOP-8597.patch > > > Similar to SequenceFiles are Apache Avro's DataFiles. Since these are getting > popular as a data format, perhaps it would be useful if {{fs -text}} were to > add some support for reading it, like it reads SequenceFiles. Should be easy > since Avro is already a dependency and provides the required classes. > Of discussion is the output we ought to emit. Avro DataFiles aren't simple as > text, nor have they the singular Key-Value pair structure of SequenceFiles. > They usually contain a set of fields defined as a record, and the usual text > emit, as available from avro-tools via > http://avro.apache.org/docs/current/api/java/org/apache/avro/tool/DataFileReadTool.html, > is in proper JSON format. > I think we should use the JSON format as the output, rather than a delimited > form, for there are many complex structures in Avro and JSON is the easiest > and least-work-to-do way to display it (Avro supports json dumping by itself). -- This message is automatically generated by JIRA.
