Вывод запроса Spark Spark не может быть показан с помощью output.show () в pyspark

/ 17 мая 2018

Я использую pyspark и хочу показать результат запроса с помощью метода .show ().Я применил тот же подход для другого запроса, и он работал отлично (т.е. я могу использовать метод show () с выводом spark.sql ('query')), но в этом случае он показывает следующую ошибку:

Traceback (последний вызов был последним): файл "/home/xxx/tas/xxx.py", строка 28, в dfWithStat.show ()

Код здесь:

import sys
from pyspark.sql import SparkSession
from pyspark.sql.functions import *
import subprocess
from pyspark.sql.types import DoubleType

spark =  SparkSession.builder.getOrCreate();
df = spark.read.option("delimiter", "\t").csv('/data/gdelt/events_2013-04-01_TO_2015-10-18.tsv')

df = df.limit(10) # can be used to here to test with 10 rows

# Register the DataFrame as a SQL temporary view to 
df.createOrReplaceTempView("sqlDataFormat")

subprocess.call(["hadoop", "fs", "-rm", "-r", "top_10_domains.csv"]) # Delete the output file if already present

#df.show()      # show all data in df in a table, in this case all are string
# Only the last column _c57 contains URLS'''

#Write sql

dfWithStat = spark.sql("""SELECT _c57 AS URL, Count(_c57) AS NumOfHits
FROM sqlDataFormat WHERE _c57 LIKE 'https://%' GROUP BY _c57
Union
SELECT _c57 as URL, Count(_c57) as NumOfHits
FROM sqlDataFormat WHERE _c57 LIKE 'http://%' GROUP BY _c57
Union
SELECT _c57 as URL, Count(_c57) as NumOfHits
FROM sqlDataFormat WHERE _c57 LIKE 'www.' GROUP BY _c57
ORDER BY NumOfHits DESC LIMIT 10""")

dfWithStat.write.csv('top_10_domains.csv')
