any tools to read sequencefile?
Hi all:
Is there any tool that can be used to read the SequenceFile or other
InputFormat/OutputFormat?
Best Wishes!

Samuel, Lukas,
Attached find the source code for our graphical sequence file viewer.
Like I said it is a quick hack but maybe you find it useful. Basically,
I took the code from Sun's "DragAndDropDemo" and modified it to call out
to a util method of ours which converts a sequence file to a string and
then displays its contents in a GUI pane. To get this to compile and run
you will need the following jars on your classpath:
commons-io.jar
commons-lang.jar
commons-logging.jar
hadoop-core.jar
log4j.jar
and of course the classes contained in your sequence file. You should
then run FileDisplay with no arguments and get a GUI which you can drop
sequence files onto, or use the file navigator to locate a file. Let me
know if it works, I had to rip this code out of our source tree so there
might be issues, but I managed to compile and run it myself with the
attached source.

Adrian,
I would be interested in this tool as well. Do you think you can send me
more info?

We have a very simple GUI that you can drag and drop sequence files onto
and it displays them. It was hacked together quite quickly so the code
quality is not amazing but if you want I could send it to you if you are
comfortable piecing it together to get it to run on your side.

thanks~
may be I don't express myself clearly
I mean any tools to show the SequenceFile as plain text or others for
reading :)

Hello Samuel
There is SequenceFileInputFormat for reading Sequence File.
