Subject Re: Need Urgent Help with Giraph-Gora
Date Wed, 04 Oct 2017 07:27:21 GMT
I need to have a readable dummy entry in Hbase to start my computation, and the Gora object
reader is not able to read it.

I try to add a dummy entry to HBase using this shell command :
 
"put 'graphGiraph', '0', 'vertices:vertexId', '0'"

And when I run my code, I get this error in the Logs :

2017-10-04 07:16:06,210 ERROR [load-0] gora.GoraVertexInputFormat (GoraVertexInputFormat.java:nextVertex(231))
- Error transforming vertices.
2017-10-04 07:16:06,210 ERROR [load-0] gora.GoraVertexInputFormat (GoraVertexInputFormat.java:nextVertex(232))
- offset (0) + length (8) exceed the capacity of the array: 1

What exactly is thebissue you are having here?
>From what I can tell all of the code looks good... is a log being
generated? Are you seeing errors? If so can you provide them?
Always remember you need to make sure any changes in your Avro schema are
compiled with the GoraCompiler.
Thanks
