Brian Hulette created BEAM-12541:
------------------------------------
Summary: fillna(value=DataFrame/Series) does not correctly fill
values
Key: BEAM-12541
URL: https://issues.apache.org/jira/browse/BEAM-12541
Project: Beam
Issue Type: Bug
Components: dsl-dataframe
Reporter: Brian Hulette
Assignee: Brian Hulette
A new doctest was added in 1.3.0 that verifies fillna with a DataFrame value:
{code}
df2 = pd.DataFrame(np.zeros((4, 4)), columns=list("ABCE"))
df.fillna(df2)
A B C D
0 0.0 2.0 0.0 0
1 3.0 4.0 0.0 1
2 0.0 0.0 0.0 5
3 0.0 3.0 0.0 4
{code}
Unfortunately, we fail this test. The root cause is that we don't require Index
partitioning when fillna is called with a DataFrame/Series value.
