> Key: MADLIB-1137
> URL: https://issues.apache.org/jira/browse/MADLIB-1137
> Project: Apache MADlib
> Issue Type: Bug
> Components: Module: Graph
> Reporter: Rahul Iyer
> Priority: Minor
> Fix For: v1.12
>
>
> Summary
> Looks like it affects:
> * APSP
> * BFS
> * SSSP
> * PageRank
> Weakly connected components does not create a <out>_summary table so that one
> seems to work
> -------------------------
> APSP: Using the example doc:
> {code}
> SELECT madlib.graph_apsp(
> 'vertex', -- Vertex table
>
>
>
> 'id', -- Vertix id column (NULL means use default naming)
>
>
>
> 'edge', -- Edge table
>
>
>
> 'src=src_id, dest=dest_id, weight=edge_weight',
>
>
>
> '"OUT_APSP"'); -- Output table of shortest paths
> ERROR: spiexceptions.SyntaxError: syntax error at or near "_summary"
> LINE 1: CREATE TABLE "OUT_APSP"_summary (
> ^
> QUERY: CREATE TABLE "OUT_APSP"_summary (
> vertex_table TEXT,
> vertex_id TEXT,
> edge_table TEXT,
> edge_args TEXT,
> out_table TEXT,
> grouping_cols TEXT)
> CONTEXT: Traceback (most recent call last):
