[SPARKML] sparkml_serving_emr_mleap_abalone.ipynb issues

https://github.com/awslabs/amazon-sagemaker-examples/blob/master/sagemaker-python-sdk/sparkml_serving_emr_mleap_abalone/sparkml_serving_emr_mleap_abalone.ipynb

I tried running this notebook depending on the kernel selected, i.e., pyspark, or conda python3 I get an error sending http request and maximum retry encountered or an import library error.

Start with sagemaker-python-sdk/sparkml_serving_emr_mleap_abalone/sparkml_serving_emr_mleap_abalone.ipynb and run it with both the pyspark and conda python3 kernels. Capture the full HTTP retry and import errors, then verify that the notebook completes its model-serving request successfully in the affected kernel(s).
