Hello,

   I'm trying to debug my code through eclipse, which worked fine with
given Hadoop applications (eg. wordcount), but as soon as I run it on my
application with my custom sequence input file/types, I get:
Java.lang.runtimeException.java.ioException (Writable name can't load class)
SequenceFile$Reader.getValeClass(Sequence File.class)

because my valueClass is customed. In other words, how can I add/build my
CustomWritable class to be with hadoop LongWritable,IntegerWritable ....
etc.

Did anyone used eclipse?

Hi,
 Please make sure that your CustomWritable has a default constructor.

Hi Madhu, it has the following line:

TermDocFreqArrayWritable () {}

but I'll try it with "public" access in case it's been called outside of my
package.

Thank you,
Mark

Unfortunately, "public" didn't change my error ... Any other ideas? Has
anyone ran Hadoop on eclipse with custom sequence inputs ?

Thank you,
Mark
