Interestingly, using {{SparkConf}} object works fine as well, > e.g.: > {code} > conf = pyspark.SparkConf() > conf.set("spark.jars.packages", > "org.mongodb.spark:mongo-spark-connector_2.11:2.2.0") > conf.set("spark.mongodb.input.uri", "mongodb://mongo/test.coll") > conf.set("spark.mongodb.output.uri", "mongodb://mongo/test.coll") > spark = pyspark.sql.SparkSession.builder\ > .appName('test-mongo')\ > .master('local[*]')\ > .config(conf=conf)\ > .getOrCreate() > {code} > The above is in Python but I've seen the behavior in other languages, though, > I didn't check R. > I also have seen it in older Spark versions. > It seems that this is the only config key that doesn't work for me via the > {{SparkSession}} builder config. > Note that this is related to creating new {{SparkSession}} as getting new > packages into existing {{SparkSession}} doesn't indeed make sense. Thus this > will only work with bare Python, Scala or Java, and not on {{pyspark}} or > {{spark-shell}} as they create the session automatically; it this case one > would need to use {{--packages}} option. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
