itholic opened a new pull request, #38673:
URL: https://github.com/apache/spark/pull/38673
### What changes were proposed in this pull request?
This PR proposes to support `bool` type for `SparkSession.builder.config`
when building the new `SparkSession`.
### Why are the changes needed?
Currently, Python `bool` type `True` or `False` is not working correctly,
since JVM side only treat the String type of "true" or "false" as a valid
option value.
So, this PR basically fix the current behavior as below:
**Before**
```python
>>> s1 = spark.builder.config("spark.sql.pyspark.jvmStacktrace.enabled",
True).getOrCreate()
>>> s1.conf.get("spark.sql.pyspark.jvmStacktrace.enabled")
'True' # invalid value, no effect for options.
```
**After**
```python
>>> s1 = spark.builder.config("spark.sql.pyspark.jvmStacktrace.enabled",
True).getOrCreate()
>>> s1.conf.get("spark.sql.pyspark.jvmStacktrace.enabled")
'true' # the lower case "true" only valid for options.
```
### Does this PR introduce _any_ user-facing change?
No.
### How was this patch tested?
Unittest added.
