--------------------------------------
Summary: Avoid runtime error in Dataset.summary() when ANSI mode
is on
Key: SPARK-38363
URL: https://issues.apache.org/jira/browse/SPARK-38363
Project: Spark
Issue Type: Sub-task
Components: SQL
Affects Versions: 3.3.0
Reporter: Gengliang Wang
Assignee: Gengliang Wang
When executing df.summary(), Spark SQL converts String columns as Double for
the
percentiles/mean/stddev metrics.
This can cause runtime errors with ANSI mode on.
Since this API is for getting a quick summary of the Dataframe, I suggest using
"TryCast" for the problematic stats so that the API still works under ANSI mode.
