Frank McQuillan updated MADLIB-1270: ------------------------------------ Fix Version/s: v1.15.1 > Unexepcted behavior in vec2cols function > ---------------------------------------- > > Key: MADLIB-1270 > URL: https://issues.apache.org/jira/browse/MADLIB-1270 > Project: Apache MADlib > Issue Type: Bug > Components: Module: Utilities > Reporter: Rashmi Raghu > Priority: Major > Fix For: v1.15.1 > > > There is some unexpected behavior when vector column to be split contains > different numbers of elements in the vectors. E.g. > Input table: > select * from test order by id; > id | t > ----+--------- > 1 | \{a,b} > 2 | \{c,d} > 3 | \{e,f} > 4 | \{g,h,i} > 5 | \{j} > (5 rows) > > select madlib.vec2cols('test','test_out_5','t',array['c1','c2','c3'],'id'); > ERROR: plpy.Error: vec2cols: Mismatch between size of vector_col and number > of cols in feature_names. > CONTEXT: Traceback (most recent call last): > PL/Python function "vec2cols", line 23, in <module> > return vec2cols_obj.vec2cols(**globals()) > PL/Python function "vec2cols", line 149, in vec2cols > PL/Python function "vec2cols", line 112, in get_names_for_split_output_cols > PL/Python function "vec2cols", line 77, in _assert > PL/Python function "vec2cols" > > select madlib.vec2cols('test','test_out_5','t',array['c1','c2'],'id'); > vec2cols > ---------- > > (1 row) > select * from test_out_5 order by id; > id | c1 | c2 > ----+----+---- > 1 | a | b > 2 | c | d > 3 | e | f > 4 | g | h > 5 | j | > (5 rows) > > > select madlib.vec2cols('test','test_out_6','t',array['c1'],'id'); > ERROR: plpy.Error: vec2cols: Mismatch between size of vector_col and number > of cols in feature_names. > CONTEXT: Traceback (most recent call last): > PL/Python function "vec2cols", line 23, in <module> > return vec2cols_obj.vec2cols(**globals()) > PL/Python function "vec2cols", line 149, in vec2cols > PL/Python function "vec2cols", line 112, in get_names_for_split_output_cols > PL/Python function "vec2cols", line 77, in _assert > PL/Python function "vec2cols" -- This message was sent by Atlassian JIRA (v7.6.3#76005)
