----------------------------------
Summary: flatten() doesn't work on ChunkedArray
Key: ARROW-7363
URL: https://issues.apache.org/jira/browse/ARROW-7363
Project: Apache Arrow
Issue Type: Bug
Affects Versions: 0.15.1
Reporter: marc abboud
Flatten() doesn't work on ChunkedArray. It returns only the ChunkedArray in a
list without flattening anything.
{code:java}
// code placeholder
aa = pa.array([[1],[2]])
bb = pa.chunked_array([aa,aa])
bb.flatten()
Out[15]:
[<pyarrow.lib.ChunkedArray object> [ [ [ 1 ], [ 2 ] ], [ [ 1 ], [ 2 ] ] ]]
Expected:
[ <pyarrow.lib.Array object> [ 1, 2 ], <pyarrow.lib.Array object> [ 1, 2 ] ]
{code}
