Subject [jira] [Commented] (GIRAPH-235) SequenceFile output format (id-value only)
Date Fri, 06 Jul 2012 15:25:35 GMT

    [ https://issues.apache.org/jira/browse/GIRAPH-235?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13408063#comment-13408063

Harsh J commented on GIRAPH-235:
--------------------------------

I wonder if:

{code}
conf.setClass("mapred.output.key.class", indexClass, Object.class);
conf.setClass("mapred.output.value.class", valueClass, Object.class);
{code}

i.e.:

{code}
job.setOutputKeyClass(Object.class);
job.setOutputKeyClass(Object.class);
{code}

can be set by GiraphJob itself. Saves you the trouble of this workaround.

> Create a SequenceFileOutputFormat for the cases where compression is important and we
only want the value of the vertex (e.g. pagerank)
