Re: Java MongoDB Spark Stratio (Please give me a hint)

The dataframe does not get any data. What could I be doing wrong here. I
have rechecked the credentials and other stuff. I am still trying to debug
the issue without any luck so far.

Any idea what I might be doing wrong. I am new to spark and I cannot
proceed forward from here:



---
 JavaSparkContext sc = new JavaSparkContext("local[*]", "test spark-mongodb
java");
SQLContext sqlContext = new SQLContext(sc);

Map options = new HashMap();
options.put("host", "host:port");
options.put("database", "database");
options.put("collection", "collectionName");
options.put("credentials", "username,database,password");

System.out.println("Check1");

DataFrame df =
sqlContext.read().format("com.stratio.datasource.mongodb").options(options).load();

df.registerTempTable("collectionName");
df.show();
