Question

我正在尝试在Hive上在spark上创建一个分区表，并使用Hive中其他表中的数据加载它。加载数据时出现以下错误：

错误：org.apache.spark.sql.AnalysisException： org.apache.hadoop.hive.ql.metadata.Table.ValidationFailureSemanticException：分区规范{cardsuit =，cardcolor =，cardSuit = SPA，cardColor = BLA} 包含非分区列;

以下是用于执行任务的命令： -

create table if not exists hive_tutorial.hive_table(color string, suit string,value string) comment 'first hive table' row format delimited fields terminated by '|' stored as TEXTFILE;

LOAD DATA LOCAL INPATH 'file:///E:/Kapil/software-study/Big_Data_NoSql/hive/deckofcards.txt' OVERWRITE INTO TABLE hive_table; --data is correctly populated(52 rows)

SET hive.exec.dynamic.partition = true;

SET hive.exec.dynamic.partition.mode = nonstrict;

create table if not exists hive_tutorial.hive_table_partitioned(color string, suit string,value int) comment 'first hive table' partitioned by (cardSuit string,cardColor string) row format delimited fields terminated by '|' stored as TEXTFILE;

INSERT INTO TABLE hive_table_partitioned PARTITION (cardSuit,cardColor) select color,suit,value,substr(suit, 1, 3) as cardSuit,substr(color, 1, 3) as cardColor from hive_table;

--alternatively i tried
INSERT OVERWRITE  TABLE hive_table_partitioned PARTITION (cardSuit,cardColor) select color,suit,value,substr(suit, 1, 3) as cardSuit,substr(color, 1, 3) as cardColor from hive_table;

数据样本： -

BLACK | SPADE | 2

BLACK | SPADE | 3

BLACK | SPADE | 4

BLACK | SPADE | 5

BLACK | SPADE | 6

BLACK | SPADE | 7

BLACK | SPADE | 8

BLACK | SPADE | 9

我正在使用spark 2.2.0和java版本1.8.0_31。

我已经检查并尝试过类似线程中给出的答案，但无法解决我的问题： - SemanticException Partition spec {col=null} contains non-partition columns

我在这里错过了什么吗？

在创建表时仔细阅读上面的脚本后，value列是分区表中的int类型，其中为原始字符串。错误误导了!!!
