HDP 3.1.0 集成 Sqoop2 踩坑问题记录
HDP 3.1.0 集成 Sqoop2 踩坑问题记录
问题一
$ sqoop:000> start job -n mysql2hdfs
2019-04-18 03:29:10 UTC: FAILURE_ON_SUBMIT
Exception: java.lang.IllegalArgumentException: Unable to parse '/hdp/apps/${hdp.version}/mapreduce/mapreduce.tar.gz#mr-framework' as a URI, check the setting for mapreduce.application.framework.path
Stack trace: java.lang.IllegalArgumentException: Unable to parse '/hdp/apps/${hdp.version}/mapreduce/mapreduce.tar.gz#mr-framework' as a URI, check the setting for mapreduce.application.framework.path
...
Caused by: java.net.URISyntaxException: Illegal character in path at index 11: /hdp/apps/${hdp.version}/mapreduce/mapreduce.tar.gz#mr-framework
...
原因：
sqoop2 未设置该环境 ${hdp.version}
解决：
修改 Ambari 组件 MapRduce2 配置
将
${hdp.version}替换成实际hdp的版本:3.1.0.0-78
| 配置项 | 参数名 | 初始值 | 修改值 |
|---|---|---|---|
| Advanced mapred-site | mapreduce.application.framework.path | /hdp/apps/${hdp.version}/mapreduce/mapreduce.tar.gz#mr-framework |
/hdp/apps/3.1.0.0-78/mapreduce/mapreduce.tar.gz#mr-framework |

原因：
Ambari 时区没有同步
解决：
利用 ntpd 同步时区

原因：
sqoop2 未设置该环境 ${hdp.version}
解决：
修改 Ambari 组件 MapRduce2 配置
将
${hdp.version}替换成实际hdp的版本:3.1.0.0-78
