------------------------------------
Summary: Drop R < 3.5 support
Key: SPARK-32073
URL: https://issues.apache.org/jira/browse/SPARK-32073
Project: Spark
Issue Type: Improvement
Components: R
Affects Versions: 3.0.0
Reporter: Hyukjin Kwon
Spark 3.0.0 is built by R 3.6.3 which does not support R < 3.5:
```
Error in readRDS(pfile) : cannot read workspace version 3 written by R 3.6.3;
need R 3.5.0 or newer version.
```
In fact, with SPARK-31918, we will have to drop R < 3.5 entirely to support R
4.0.0.
This JIRA targets to drop R < 3.5 in SparkR.
