UDF无法在Spark SQL中工作

标签: scala hive apache-spark shark-sql

我试图在Spark SQL上计算Jaccard索引。我在Hive上的表格包含以下数据:

hive> select * from test_1;

1   ["rock","pop"]
2   ["metal","rock"]

表DDL:

create table test_1
(id int, val array<string>);

我正在使用Brickhouse中的UDF。从spark-shell开始,我可以执行以下命令来创建临时函数。

val hiveContext = new org.apache.spark.sql.hive.HiveContext(sc)
hiveContext.hql("CREATE TEMPORARY FUNCTION jaccard_similarity AS 'brickhouse.udf.sketch.SetSimilarityUDF'")

我还将.jar文件添加到CLASSPATH的{​​{1}}(spark-shell)。

当我列出这些功能时,我能够看到我创建的新功能。

compute-classpath.sh

接下来,我使用hiveContext.hql("show functions").collect().foreach(println) 函数计算jaccard_similarity数组的Jaccard索引。

val

我收到以下错误:

hiveContext.hql("select jaccard_similarity(a.val, b.val) from test_1 a join test_1 b")

我无法找到对Spark SQL不支持的 protected lazy val arrayType: Parser[DataType] = "ArrayType" ~> "(" ~> dataType ~ "," ~ boolVal <~ ")" ^^ { case tpe ~ _ ~ containsNull => ArrayType(tpe, containsNull) 的任何引用。如果有人能分享关于如何使其发挥作用的任何指示,那就太好了。

此外,该功能可以从array shell完美运行。

更新(8月5日):

我只是在Github的Master分支上构建Spark。错误消息包含更多信息(例如Hive而不是scala.MatchError: ArrayType(StringType,false)

抱歉,我在StackOverflow上的声誉不足以发表评论。希望这个&#34;回答&#34;很好。无论如何,我使用HiveContext在SparkSQL上玩,并注意到与ArrayType类似的行为。虽然它不能解决您的问题,但它可以解释原因

事实证明,当使用spark&#34; internal&#34;时,HiveContext(Spark 1.1.0)支持ArrayType。表结构。每当你试图访问spark&#34; external&#34; hive表(即托管在Metastore上),您可能会遇到类似不支持ArrayType的问题..

这是一个简单的插图

// ************
// ArrayType is supported when playing with SparkSQL temp tables...
// ************

val sqlContext = org.apache.spark.sql.hive.HiveContext(sc)
val rdd = sqlContext.jsonFile("/tmp/test.json")
rdd.printSchema
/*
    root
    |-- id: integer (nullable = true)
    |-- names: array (nullable = true)
    |    |-- element: string (containsNull = false)
*/

sqlContext.registerRDDAsTable(rdd,"test")
val out = sqlContext.sql("SELECT names FROM test")

// ************
// ...But fail on Hive statements
// ************

sqlContext.sql("CREATE TABLE mytable AS SELECT names FROM test")

/*
    org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 5.0 failed 4 times, most recent failure: Lost task 0.3 in stage 5.0 (TID 16, vagrant): scala.MatchError: ArrayType(StringType,true) (of class org.apache.spark.sql.catalyst.types.ArrayType)

.../...
*/

我仍然不知道它失败的确切原因和原因,但HiveContext没有(完全)支持ArrayType。 无论如何,我怀疑你在这里描述的问题与你的jaccard UDF功能有关..

或者,使用这样一个(工作)丑陋的黑客:)

sqlContext.sql("CREATE TABLE mytable AS SELECT split(concat_ws('#',names),'#') FROM test")
