Akmal Chaudhri commented on IGNITE-7655:
----------------------------------------

[~vkulichenko], I am trying to take the existing Scala code example:

[https://github.com/apache/ignite/blob/master/examples/src/main/spark/org/apache/ignite/examples/spark/IgniteDataFrameExample.scala]

and rewrite it for Java. I am blocked here for the moment:
{code:java}
val igniteDF = spark.read
.format(FORMAT_IGNITE) //Data source type.
.option(OPTION_TABLE, "person") //Table to read.
.option(OPTION_CONFIG_FILE, CONFIG) //Ignite config.
.load()
.filter(col("id") >= 2) //Filter clause.
.filter(col("name") like "%M%") //Another filter clause.
{code}
The Java code to create the tables works ok. However, I don't know Scala, so 
trying to do a conversion from one language to another is difficult.
