hadoop - How can i import a column type SDO_GEOMETRY from Oracle to HDFS with Sqoop? -


issue

i'm using sqoop fetch data oracle , put hdfs. unlike other basic datatypes understand sdo_geometry meant spatial data.

my sqoop job fails while fetching datatype sdo_geometry.

need import column shape sdo_geometry datatype oracle hdfs.

i have more 1000 tables has sdo_geometry datatype , how can handle datatype in general while sqoop imports happen ?

i have tried --map-column-java , --map-column-hive , still error.

error :
error tool.importtool: encountered ioexception running import job: java.io.ioexception: hive not support sql type column shape

sqoop command

below sqoop command have :

sqoop import --connect 'jdbc:oracle:thin:xxxxx/xxxxx@(description=(address=(protocol=tcp)(host=xxxxxxx)(port=1521))(connect_data=(sid=xxxxx)))' -m 1 --create-hive-table --hive-import --fields-terminated-by '^' --null-string '\\\\n' --null-non-string '\\\\n' --hive-overwrite --hive-table prod.plan1   --target-dir test/plan1  --table prod.plan  --map-column-hive se_xao_cad_data=binary --map-column-java shape=string --map-column-hive shape=string --delete-target-dir

the default type mapping sqoop provides between relational databases , hadoop not working in case why sqoop job fails. need override mapping geometry datatypes not supported sqoop.

use below parameter in sqoop job

syntax:--map-column-java col1=javadatatype,col2=javadatatype.....

sqoop import  .......  ........  --map-column-java columnnameforsdo_geometry=string

as column name shape 

--map-column-java shape=string
