Graph

Procedure

1. Enter the console and run odpscmd.
2. Create input and output tables

   create table sssp_in (v bigint, es string);
   create table sssp_out (v bigint, l bigint);

   See creating more statements for tables in Table Operations.

3. Upload Data.
   The content of local data is as follows:

   2, 2, 3, 4, 4
   2 1:2,3:2,4:1
   3 1:1,2:2,5:1
   4 1:4,2:1,5:1
   5 3:1,4:1

   The tab button is used to separate two columns.

   tunnel u -fd " " sssp.txt sssp_in;

4. Write SSSP example.
   According to the introduction in Graph Eclipse Plug-in, compile and debug SSSP Example on local. In this example, we assume the code is packaged as odps-graph-example-sssp.jar.

   Note You only need to package the SSSP code. You do not need to package the SDK in odps-graph-example-sssp.jar.
5. Add Jar package.

   add jar $LOCAL_JAR_PATH/odps-graph-example-sssp.jar

   Note For resource creation, see Resource Operation.
6. Run SSSP.

   jar -libjars odps-graph-example-sssp.jar -classpath $LOCAL_JAR_PATH/odps-graph-example-sssp.jar com.aliyun.odps.graph.example.SSSP 1 sssp_in sssp_out;

   The jar command is used to run MaxCompute Graph jobs in the same way as the command for running MapReduce jobs.

   When Graph job is running, the corresponding instance ID, execution schedule and result summary are printed on the command line

   as follows:

   ID = 20130730160742915gl205u3
