Question

我正在运行CDH 5.4，使用Spark 1.3.0和Spark on YARN支持。当我在HIVE中创建一个简单的镶木桌，然后尝试使用PySpark执行转换或聚合时，它会向我抛出此错误消息。有什么想法吗？要重现此问题，请执行以下操作...

HIVE：

CREATE TABLE IF NOT EXISTS TestTable_Parquet(
Investment_Id int,
Identifier string,
Package_Id int,
AsOfDate timestamp
) STORED AS PARQUET
;
INSERT INTO TABLE TestTable_Parquet
VALUES (1, "id1", 1, "2015-01-01")
;

PySpark：

test = sqlCtx.table("testtable_parquet")
test.filter(test.identifier == "id1")

错误

经过一段时间的播放后，问题的解决方案似乎首先运行此set conf命令，这只在您希望Spark与Hive通信时才需要：

sqlCtx.setConf("spark.sql.hive.convertMetastoreParquet", "false")
