Subject RE: lookup and set partitions for a graph processing job
Date Mon, 12 Oct 2015 16:33:26 GMT
Hi,

I have a follow-up question. Are there any tutorials/examples available that show I can use
my own custom graph partitioner for Giraph?

Thanks
Muntasir.

There is no explicit API, but there is an option to set the partitioning strategy, which is
giraph.graphPartitionerFactoryClass. The value of that option is set to HashPartitionerFactory
by default. So you can look up this class and it will give you some information about the
mapping you are looking for.

Hi,

I am new to Giraph and have a question about the partitioning API in Giraph. Does Giraph have
an explicit API to lookup the current partition for a running job (vertex to server mapping),
and setting the partition for a new job?

Regards
Muntasir.
