我正在尝试使用pyspark将Dataframe写入hbase。

from pyspark import SparkContext
from pyspark.sql import SQLContext

sc = SparkContext()
sqlc = SQLContext(sc)

data_source_format = 'org.apache.spark.sql.execution.datasources.hbase'

df = sc.parallelize([('a', '1.0'), ('b', '2.0')]).toDF(schema=['col0', 'col1'])

catalog = ''.join("""{
    "table":{"namespace":"default", "name":"testtable"},
    "rowkey":"key",
    "columns":{
        "col0":{"cf":"rowkey", "col":"key", "type":"string"},
        "col1":{"cf":"cf", "col":"col1", "type":"string"}
    }
}""".split())

df.write.options(catalog=catalog).format(data_source_format).save()

正在执行以下格式的命令：

sudo spark-submit --packages com.hortonworks:shc-core:1.1.1-2.1-s_2.11 --repositories http://repo.hortonworks.com/content/groups/public/  --files /home/chenxx/hbase/conf/hbase-site.xml sogou4.py

spark版本：2.3.0 hadoop版本：2.7.6 hbase版本：1.1.5 scala版本：2.11.6
错误：

有人知道问题出在哪里吗？如果有什么建议，我将不胜感激！谢谢！
