在日常操作中,我将数据从postgresql导入hdfs,并将hdfs导入s3(sqoop import[postgres to hdfs]&distcp[from hdfs to s3])
我想删除中间步骤(hdfs)并使用sqoop直接将数据导入s3 bucket。
但是,相同的sqoop字符串在导入操作结束时失败。
sqoop import
-Dmapreduce.map.memory.mb="8192"
-Dmapreduce.map.java.opts="-Xmx7200m"
-Dmapreduce.task.timeout=0
-Dmapreduce.task.io.sort.mb="2400"
--connect $conn_string$
--fetch-size=20000
--username $user_name$
--p $password$
--num-mappers 20
--query "SELECT * FROM table1 WHERE table1.id > 10000000 and table1.id < 20000000 and \$CONDITIONS"
--hcatalog-database $schema_name$
--hcatalog-table $table_name$
--hcatalog-storage-stanza "STORED AS PARQUET LOCATION s3a://path/to/destination"
--split-by table1.id
我也试过了 --target-dir s3a://path/to/destination
而不是 ....... LOCATION s3a://path/to/destination
在“Map:%100已完成”之后,它将抛出以下错误消息:

sqoop尝试在导入作业完成后重命名s3文件夹,这是不可能的,因为s3的体系结构是对象存储。
我发现这个问题已经在sqoop1.4.7中解决了*
