Open Source Data Lake & External Python Integration

Hello everyone,

Has anybody worked on Open Source Apache Hadoop based Data Lake integrated with external Python 3.x version?

We have the Data Lake with default Python 2.7 version . We however, want to use the latest version of Python so trying to find a way to connect the same. Also, is there a way we utilise external Python for Processing but consume memory from Data Lake?

Our Python server isnt big enough to handle multiple jobs, hence this question.
Please guide.

Many thanks,
Pallavi
