why does pyspark give "we couldn't find any external ip address" on macos?

You can explicitly set the local hostname to localhost (which is probably resolvable) for spark-shell using SPARK_LOCAL_HOSTNAME environment variable as follows:

SPARK_LOCAL_HOSTNAME = localhost. / bin / spark - shell

Or:

. / bin / spark - shell - c spark.driver.host = localhost

Add local path in $SPARK_HOME/conf/spark-env.sh:

SPARK_LOCAL_IP = 127.0 .0 .1

I use pyspark and got a warning below. Could someone tell me how to fix it? Is this something I should be worried about?,Why Does Pyspark Give We Couldnt Find Any External Ip Address On Macos, 2 days ago The Spark shell and spark-submit tool support two ways to load configurations dynamically. The first is command line options, such as --master, as shown above. spark-submit can accept any … , If it doesn’t find it, then the Python code is not recognized as an internal or external command, operable program or batch file message is displayed. It is not common for users programming on computers such as a Mac to see this error, since Python comes pre-installed on macOS.
