Extract sheet names using pyspark about spark-excel

[nightscape]

Does this help? #196 (comment)

Oh, I tested it on "legacy" Databricks Cluster and it works.

My code:

reader = spark._jvm.com.crealytics.spark.excel.WorkbookReader.apply({"path": 'my_file.xlsx'}, spark.sparkContext._jsc.hadoopConfiguration())

d = reader.sheetNames()

print(d)

In Unity Catalog environment i'm getting error (it's directly related to Cluster Mode, it cannot be changed in my case):

py4j.security.Py4JSecurityException: Method public org.apache.hadoop.conf.Configuration org.apache.spark.api.java.JavaSparkContext.hadoopConfiguration() is not whitelisted on class class org.apache.spark.api.java.JavaSparkContext

Is there any other way to get sheet names, without WorkbookReader constructor? I'd rather not mixing crealytics spark code with pandas or any other library.
