snappydata无法使用Java的Smart Connector从现有Spark安装访问SnappyData存储

时间:2017-06-06 01:08:06

标签: java snappydata

我尝试通过智能连接器样式连接到SnappyData商店作为http://snappydatainc.github.io/snappydata/howto/#how-to-access-snappydata-store-from-an-existing-spark-installation-using-smart-connector中的描述,但是由java.nio.BufferUnderflowException引起了com.gemstone.gemfire.SerializationException root。

这是stacktrace:

以下是代码:

public class SmartConnectorMain{
public static void main(String [] args){

    SparkSession spark = SparkSession
            .builder()
            .appName("SmartConnectorMainJava")
            .master("snappydata://host-01:9999,host05-:9999")
            .config("snappydata.store.locators", "host-01:9999,host-05:9999")
            .getOrCreate();

    JavaSparkContext jsc = new JavaSparkContext(spark.sparkContext());
    SnappySession snappy = new SnappySession(spark.sparkContext());

    println(" ####  Creating a table TestColumnTable  #### \n");

    snappy.dropTable("TestColumnTable",  true);

    DataSet<Row> dataFrame = snappy.range(1000).selectExpr("id", "floor(rand() * 10000) as k");

    snappy.sql("create table TestColumnTable (id bigint not null, k bigint not null) using column");


    println(" ####  Write to table completed. ### \n\n" +
            "Now you can query table TestColumnTable using $SNAPPY_HOME/bin/snappy-shell");
}

private static void println(String s){
    System.out.println(s);
}

答案 0 :(得分:0)

问题似乎是您的SnappyData定位器和Spark主URL使用相同的主机和端口。我使用来自https://spark-packages.org/package/SnappyDataInc/snappydata的spark包0.8-s_2.11快速验证了SnappyData 0.8版本和Spark2.0本地模式集群。

我也可以通过snappy-sql shell查询表。 以下是我的计划enter image description here
