问题
For the life of me I cannot figure out what is wrong with my PySpark install. I have installed all dependencies, including Hadoop, but PySpark cant find it--am I diagnosing this correctly?
See the full error message below, but it ultimately fails on PySpark SQL
pyspark.sql.utils.IllegalArgumentException: u"Error while instantiating 'org.apache.spark.sql.hive.HiveSessionStateBuilder':"

tl;dr Close all the other Spark processes and start over.
The following WARN messages say that there is another process (or multiple processes) that holds the ports.
I'm sure that the process(es) are Spark processes, e.g. pyspark sessions or Spark applications.
17/10/24 21:21:59 WARN Utils: Service 'SparkUI' could not bind on port 4040. Attempting port 4041.
17/10/24 21:21:59 WARN Utils: Service 'SparkUI' could not bind on port 4041. Attempting port 4042.
17/10/24 21:21:59 WARN Utils: Service 'SparkUI' could not bind on port 4042. Attempting port 4043.
That's why after Spark/pyspark has found that the port 4044 is free to use for web UI it tried to instantiate HiveSessionStateBuilder and failed.
pyspark failed as you cannot have more than one Spark application up and running that uses the same local Hive metastore.

WHY THIS HAPPENS ?
Because we try to create new session more than once ! on different tabs of browser of jupyter notebook.
Solution :
START NEW SESSION ON SINGLE TAB IN JUPYTER NOTEBOOK AND AVOID TO CREATE NEW SESSION ON DIFFRENT TABS
from pyspark.sql import SparkSession
spark = SparkSession.builder.appName('EXAMPLE').getOrCreate()
回答3:
Another possible cause is that the spark application failed to start due to minimum machine requirements were not attended.
In the Application history tab:
Diagnostics:Uncaught exception: org.apache.hadoop.yarn.exceptions.InvalidResourceRequestException: Invalid resource request, requested virtual cores < 0, or requested virtual cores > max configured, requestedVirtualCores=5, maxVirtualCores=4
