Pregel: BTreeDuplicateKeyException: Trying to insert duplicate key into leaf node #102

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
When I use pregel to run a big file, it throws BTreeDuplicateKeyException: 
Trying to insert duplicate key into leaf node. But the key from file is unique 
and I never change vertexId. Here attached the exception file. 
My branch is fullstack_genomix. After you do mvn clean package in this branch, 
you can run pregel job MergeGraphVertex using this command line: bin/pregelix 
genomix-pregelix-0.2.4-SNAPSHOT-jar-with-dependencies.jar 
edu.uci.ics.genomix.pregelix.MergeGraphVertex -inputpaths input -outputpath 
result -ip 127.0.0.1 -port 3099 -kmer-size 55. 
Please feel free to get the big file from me. My email is anbangx@gmail.com.

It was due to the fact there are duplicate vertex in the input file.
I filed another issue for BTree bulkload enhancement: issue102.
