Sqoop while used with HCatalog import not able to remove new line (\n) from column data even after using --hive-drop-import-delims option in the command when running Apache Sqoop with Oracle.
Sqoop Query:
sqoop import --connect jdbc:oracle:thin:@ORA_IP:ORA_PORT:ORA_SID \
--username user123 --password passwd123 -table SCHEMA.TBL_2 \
--hcatalog-table tbl2 --hcatalog-database testdb --num-mappers 1 \
--split-by SOME_ID --columns col1,col2,col3,col4 --hive-drop-import-delims \
--outdir /tmp/temp_table_loc --class-name "SqoopWithHCAT" \
--null-string ""
Data in Oracle Column col4 as below: (Data has control characters such as ^M)
<li>Details:^M
<ul>^M
<li>
Does Control character causing this problem?
Am I missing anything ? Is there any workaround or solution for this problem?
Use --map-column-java
option to explicitly state the column is of type String
. Then --hive-drop-import-delims
works as expected (to remove \n
from data).
Changed Sqoop Command :
sqoop import --connect jdbc:oracle:thin:@ORA_IP:ORA_PORT:ORA_SID \
--username user123 --password passwd123 -table SCHEMA.TBL_2 \
--hcatalog-table tbl2 --hcatalog-database testdb --num-mappers 1 \
--split-by SOME_ID --columns col1,col2,col3,col4 --hive-drop-import-delims \
--outdir /tmp/temp_table_loc --class-name "SqoopWithHCAT" \
--null-string "" --map-column-java col4=String
