Hello @Edu7478 This seems to be a common issue faced during high concurrency when there is no control on how much memory a query can utilise. You can check below : - all tables has updated stats - configure / fine tume Impala Admission Control

I believe that issue you are facing here is due to column type Geometry When data is present in HDFS , thought is mapped to a Hive Table, particular column must be in STRING which is incompatible with Geometry type column in destination postgres, Only option we have is to alter the column type to VARCHAR at postgres

This issue doesn't seems to be driver dependent , but moreover conversion of Geometry data type to Java compatible data type (string could be the best suited for mixed data types) For now you can cast Geometry column to VarChar in a select query and pass the same query in sqoop import command using "--query <sql_query>" tag

Check column type for table geom. During runtime sqoop was not able to identify data in column geom causing this issue Workaround : add --map-column-java geom string https://docs.cloudera.com/sqoop/1.4.7.7.1.6.0/user-guide/index.html#_controlling_type_mapping
