When I tried to use hail 0.2, it says:
Py4JJavaError: An error occurred while calling z:is.hail.HailContext.apply.
: is.hail.utils.HailException: This Hail JAR was compiled for Spark 2.2.0, cannot run with Spark 2.4.0.
When I change the spark version to 2.2.0, it shows the following message in the end:
Java gateway process exited before sending its port number
What should I do?
