Question

我正在尝试使用sqoop job as，

将postgres sql中的增量数据导入到hdfs的目录中

sqoop job --create incident_import -- import --connect jdbc:postgresql://IP ADDRESS:5432/Analyst_Bangalore --username postgres  --password track@123 --map-column-java the_geom=String   --table incident -m 1  --warehouse-dir /user/hive/warehouse/analyst_bangalore.db --incremental lastmodified --check-column incident_start_time --last-value "2016-08-03 14:33:48.087"   --driver org.postgresql.Driver  -- --schema analyst

如果我正在执行这项工作，它会给出ERROR，

sqoop job -exec incident_import

org.postgresql.util.PSQLException: ERROR: relation "incident" does not exist

任何人都有任何想法请与我分享。这需要一点点。

从postgres到HDFS的Sqoop增量导入正在给出org.postgresql.util.PSQLException
