Haejoon Lee updated SPARK-37657:
--------------------------------
Description:
Initialized in Koalas issue: [https://github.com/databricks/koalas/issues/1888.]
The `DataFrame.describe()` in pandas API on Spark doesn't work properly when
DataFrame has no numeric column.
{code:java}
>>> df = ks.DataFrame({'a': ["a", "b", "c"]}) >>> df.describe() Traceback (most
>>> recent call last): File "<stdin>", line 1, in <module> File
>>> "/.../koalas/databricks/koalas/frame.py", line 7582, in describe raise
>>> ValueError("Cannot describe a DataFrame without columns") ValueError:
>>> Cannot describe a DataFrame without columns
{code}
As it works fine in pandas, we should fix it.
