pyspark failed to read in csv file. WARN FileStreamSink: Assume no metadata directory. java.net.ConnectException: Connection refused;

I'm trying to read csv file using pyspark.
Before I installed Hadoop, I was able to read in the file using pyspark. However, after I changed my java version to java8 and installed Hadoop, I couldn't read in the file and an error poped out as following. I only changed java version and JAVA_HOME during installation. It seems that some settings have been changed. I'm new to pyspark and hadoop. I tried to see connection refused but still have no idea. Could you please tell me where should I start to check?

Thank you very much in advance!
