Subject: [mongodb-user] Re: MongoDB Spark Connector - how
to create an RDD using the python connector
The documentation on the python connector seems to indicate that the mongo documents to be read into Spark using the python connector must have a defined schema.
You don’t have to define a schema. For example, in PySpark you can execute as below:
df = sqlContext.read.format("com.mongodb.spark.sql.DefaultSource")
# Print first record
# Get RDD from Dataframe
myRDD = df.rdd
I’ve tried out the MongoDB Spark connector and have run into issues with the python connector.
If you have an issue using MongoDB Spark connector (Python), please provide:
- MongoDB Spark Connector version
- Spark version
- Snippet code enough to reproduce the issue
- Any error messages that you’re getting
