Hi, Below is my code and result where I am trying to query IgniteRDD through SQL statement with scala at Zeppelin. First I use restful API to put a pair of data(key=10, val=45) into Ignite cache.
%python import requests requests.put("http://127.0.0.1:8080/ignite?cmd=put&key=10&val=45&cacheName=zeppelincache") Result: <Response [200]> Then I execute the code below. %spark import org.apache.ignite.configuration._ import org.apache.ignite.spark._ val ic = new IgniteContext(sc,()=>new IgniteConfiguration()) val sharedRDD2 = ic.fromCache[Integer,Integer]("zeppelincache") sharedRDD2.savePairs(sc.parallelize(1 to 3, 3).map(i => (i, i*2))) sharedRDD2.collect sharedRDD2.sql("select * from Integer").show() Result: import org.apache.ignite.configuration._ import org.apache.ignite.spark._ ic: org.apache.ignite.spark.IgniteContext = org.apache.ignite.spark.IgniteContext@7a017337 sharedRDD2: org.apache.ignite.spark.IgniteRDD[Int,Int] = IgniteRDD[136] at RDD at IgniteAbstractRDD.scala:32 res129: Array[(Int, Int)] = Array((1,2), (2,4), (3,6), (10,45)) +----+----+ |_KEY|_VAL| +----+----+ | 1| 2| | 2| 4| | 3| 6| +----+----+ 1. Why can the collect command get the pair (10,45) but SQL statement can’t? 2. How to get the pair (10,45) through SQL statement?
