stsClient issue with private notebook #141
Description
Customer was using PySpark SDK with a notebook without public internet access, they configured the notebook in a way to connect to their regional sts endpoint not the global one, when initializing the KMeansSageMakerEstimator, the stsClient is default to the global one which is causing a time out error. How could they modify the stsClient so they can connect to their regional sts endpoint instead?
