如何使用sqoop在hive中创建多级分区

标签： hive sqoop

我需要使用Sqoop创建具有三个分区年/月/日的hive表。我在sqoop中检查了 - hive-partition-key 和 - hive-partition-value 。使用这些参数我创建了分区年，就像这样--hive-partition-key year --hive-partition-value '2016' 我的问题是如何为partition-key和partition-value传递多个值来创建年/月/日等分区。 

sqoop import --connect jdbc:postgresql://localhost:7432/test_db \
  --driver org.postgresql.Driver --username pgadmin --password pgadmin@1234 \
  --table user1  \
  --fields-terminated-by '\001' \
  --lines-terminated-by '\012' \
  --hcatalog-database test \
  --hcatalog-table user1 \
  --hcatalog-partition-keys year,month,day \
  --hcatalog-partition-values '2016,08,15' \
  --verbose

更新了命令：

sqoop import --connect jdbc:postgresql://localhost:7432/test_db \
  --driver org.postgresql.Driver --username pgadmin --password pgadmin@1234 \
  --table user1  \
  --create-hcatalog-table \
  --hcatalog-table user1 \
  --hcatalog-partition-keys year,month,day \
  --hcatalog-partition-values '2016,08,15' \
  --verbose

更新命令后出错

为了使用Sqoop将数据导入多键分区Hive表，您可以使用hcatalog-table feature

例如，在您的情况下，您可以使用以下内容：

(...) --hcatalog-table <your_table_name> --hcatalog-partition-keys year,month,day
 --hcatalog-partition-values 2016,07,01

根据documentation：

  

这两个选项用于指定多个静态分区   键/值对。在以前的版本中， - hive-partition-key和   --hive-partition-value选项用于指定静态分区键/值对，但仅指定一级静态分区键   可以提供。选项--hcatalog-partition-keys和   --hcatalog-partition-values允许将多个键和值作为静态分区键提供。多个选项值   以（逗号）分隔。例如，如果hive分区键为   要导出/导入的表是使用分区键名定义的   年份，月份和日期以及年份= 1999的特定分区，   month = 12，day = 31是所需的分区，然后是两个的值   选项如下：

     

- hcatalog-partition-keys年，月，日   --hcatalog-partition-values 1999,12,31

我们需要在步骤中实现这一点。在此更新的命令上：在上面标记您正在做两件事。

创建新的表和sqooping数据，根据我的观察，由于我们必须使用sqoop创建多级分区，因此这一次将不起作用。

因此，首先创建只是使用hcatalogue创建ddl以支持多级分区。

步骤1：

sqoop import \
--connect jdbc:oracle:thin \
--username xxxx \
--password yyyy \
--query  'select EMPNO,ENAME,MGR,HIREDATE,SAL,COMM from  t_test_emp  where  $CONDITIONS AND 1=2' \
--create-hcatalog-table \
--hcatalog-database db1 \
--hcatalog-table test_part1 \
--hcatalog-partition-keys  DEPTNO,JOB \
--hcatalog-partition-values  1,1 \
-m 1

步骤2： 现在插入数据：

sqoop import \
--connect jdbc:oracle:thin:  \
--username xxxx  \
--password yyyy \
--table t_test_emp \
--columns EMPNO,DEPTNO,ENAME,JOB,MGR,HIREDATE,SAL,COMM \
--hcatalog-database db1 \
--hcatalog-table test_part1 \
-m 1

它会工作..
