Example fail when performing sparse matrices addition
-----------------------------------------------------
Key: HAMA-238
URL: https://issues.apache.org/jira/browse/HAMA-238
Project: Hama
Issue Type: Bug
Components: examples
Affects Versions: 0.2.0
Reporter: Edward J. Yoon
Assignee: Edward J. Yoon
Priority: Minor
Fix For: 0.2.0
Hi there
Have following working setup:
hadoop 0.20.1
hbase 0.20.3
hama latest SVN trunk version
Notes:
had to replace and rebuild hama with new hbase lib (upgraded to version
0.20.3)
1. successfully rand hama example to generate random matrix
$HAMA_HOME/bin/hama examples rand -m 10 -r 10 100 100 30.5% matrixA
Note: verified hbase table was generated (via shell list and scan)
2. moved on to other examples, generated 2 random matrices:
$HAMA_HOME/bin/hama examples rand -m 10 -r 10 100 100 30.5% matrixA
$HAMA_HOME/bin/hama examples rand -m 10 -r 10 100 100 30.5% matrixB
then an attempt at distributed addition:
$HAMA_HOME/bin/hama examples add1 matrixA matrixB
3. in similar venue tried multi, norms and and similarity (all generated
exceptions)
Exceptions appear to be hama code related (and not environmentally specific)
Culprit could be in improper usage of input matrix data to add,multi, norms
and similarity.
Another question is about lack of "breadth first search" sample, is this a
sub-project of next release?
thanks
