问题描述
当前，我正在尝试使用Python的Pixiedust软件包将数据从笔记本存储到Cloudant DB中.建立连接后，尝试向数据库中插入数据时会出现此错误.
Currently I am trying to stash data into Cloudant DB from a notebook using Python's Pixiedust package. After establishing a connection it gives me this error when trying to insert data into the database.
nPy4JJavaError: An error occurred while calling o172.save.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 3 in stage 38.0 failed 10 times, most recent failure: '
Lost task 3.9 in stage 38.0 (TID 1811, yp-spark-dal09-env5-0046): spray.http.IllegalUriException: The path of an URI without authority must not begin with "//"
