redis.clients.jedis.exceptions.JedisConnectionException: Unexpected end of stream

[evbo]

It does not seem possible to start and stop the embedded redis database within separate, isolated unit tests that implement redislabs' Spark Redis.

The second unit test below fails with: redis.clients.jedis.exceptions.JedisConnectionException: Unexpected end of stream

import com.holdenkarau.spark.testing.SharedSparkContext
import com.redislabs.provider.redis.{RedisConfig, RedisEndpoint}
import org.junit.runner.RunWith
import org.scalatest.junit.JUnitRunner
import org.scalatest.{BeforeAndAfterEach, FlatSpec, Matchers}
import redis.embedded.RedisServer

@RunWith(classOf[JUnitRunner])
class RedisSpec extends FlatSpec with SharedSparkContext with BeforeAndAfterEach with Matchers {
  
  "first test" should "connect and close redis" in {
    val redisEmbedded = new RedisServer(6379)
    redisEmbedded.start()
    val redisConfig = new RedisConfig(new RedisEndpoint("localhost", 6379))
    redisEmbedded.stop()
  }

  "second test" should "also connect and close redis" in {
    val redisEmbedded = new RedisServer(6379)
    redisEmbedded.start()
    // fails here:
    val redisConfig = new RedisConfig(new RedisEndpoint("localhost", 6379))
    redisEmbedded.stop()
  }
}
