Running PySpark in a Virtual Environment
For many PySpark applications, it is sufficient to use
specify dependencies. However, there are times when
inconvenient, such as the following scenarios:
A large PySpark application has many dependencies, including transitive dependencies.
A large application needs a Python package that requires C code to be compiled before installation.
You want to run different versions of Python for different applications.
For these situations, you can create a virtual environment as an isolated Python runtime environment. HDP supports VirtualEnv for PySpark in both local and distributed environments, easing the transition from a local environment to a distributed environment.
This feature is currently only supported in YARN mode.
