我正在尝试将增量数据从postgressql导入hdfs的目录，使用sqoop作业作为，

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

如果我在执行这个任务，它给出的错误是，

sqoop job -exec incident_import

任何人有任何想法请与我分享。这是一个小的要求。
