I would like to import data from Oracle to Hive by using Sqoop as Parquet file.
I have been trying to import data using sqoop using the following command:
sqoop import --as-parquetfile --connect jdbc:oracle:thin:#10.222.14.11:1521/eservice --username MOJETL --password-file file:///home/$(whoami)/MOJ_Analytic/moj_analytic/conf/.djoppassword --query 'SELECT * FROM CMST_OFFENSE_RECORD_FAMILY WHERE $CONDITIONS' --fields-terminated-by ',' --escaped-by ',' --hive-overwrite --hive-import --hive-database default --hive-table tmp3_cmst_offense_record_family --hive-partition-key load_dt --hive-partition-value '20200213' --split-by cmst_offense_record_family_ref --target-dir hdfs://nameservice1:8020/landing/tmp3_cmst_offense_record_family/load_dt=20200213
I get the following error:
ERROR sqoop.Sqoop: Got exception running Sqoop: org.kitesdk.data.ValidationException: Dataset name default.tmp3_cmst_offense_record_family is not alphanumeric (plus '_')
org.kitesdk.data.ValidationException: Dataset name default.tmp3_cmst_offense_record_family is not alphanumeric (plus '_')
I've tried to remove
sqoop import --as-parquetfile --connect jdbc:oracle:thin:#10.222.14.11:1521/eservice --username MOJETL --password-file file:///home/$(whoami)/MOJ_Analytic/moj_analytic/conf/.djoppassword --query 'SELECT * FROM CMST_OFFENSE_RECORD_FAMILY WHERE $CONDITIONS' --fields-terminated-by ',' --escaped-by ',' --split-by cmst_offense_record_family_ref --target-dir hdfs://nameservice1:8020/landing/tmp3_cmst_offense_record_family/load_dt=20200213
I still got the same error.
ERROR sqoop.Sqoop: Got exception running Sqoop: org.kitesdk.data.ValidationException: Dataset name load_dt=20200213 is not alphanumeric (plus '_')
org.kitesdk.data.ValidationException: Dataset name load_dt=20200213 is not alphanumeric (plus '_')
Please try rewriting this part:
--hive-table default.tmp3_cmst_offense_record_family
with this one:
--hive-table tmp3_cmst_offense_record_family
You already specified the database name with the clause --hive-database
When I am trying to import a table to Hive, I am getting a strange error.
Query:
sqoop import --connect 'jdbc:sybase:Tds:10.100.*.***:5500/DATABASE=****' --driver 'com.sybase.jdbc3.jdbc.SybDriver' --username "****" --password "***" --table dw.dm_court_courttype --direct -m 1 --hive-import --create-hive-table --hive-table DM_court_courtcype --target-dir "/user/hive/warehouse/DM_Court_CourtType" --verbose

Don't use database name with table name.
Use --table dm_court_courttype instead of
--table dw.dm_court_courttype
Try this:
sqoop import --connect 'jdbc:sybase:Tds:10.100..:5500/DATABASE=****' --driver 'com.sybase.jdbc3.jdbc.SybDriver' --username "****" --password "*" --table dm_court_courttype --direct -m 1 --hive-import --create-hive-table --hive-table DM_court_courtcype --target-dir "/user/hive/warehouse/DM_Court_CourtType" --verbose
I am using the sqoop 1.4.4 to transfer data from oracle to hive, using sentence:
sqoop job --create vjbkeufwekdfas -- import --split-by "Birthdate"
--check-column "Birthdate" --hive-database chinacloud --hive-table hive_vjbkeufwekdfas --target-dir /tmp/vjbkeufwekdfas --incremental lastmodified --username GA_TESTER1 --password 123456 --connect jdbc:oracle:thin:#172.16.50.12:1521:ORCL --query "SELECT \"Name\",\"ID\",\"Birthdate\" FROM GA_TESTER1.gmy_table1 where \$CONDITIONS" --m 1 --class-name vjbkeufwekdfas --hive-import
--fields-terminated-by '^X' --hive-drop-import-delims --null-non-string '' --null-string ''
it doesn't work, cause the sqoop use checking strategy in the tool.ImportTool
16/10/08 14:58:03 INFO orm.CompilationManager: Writing jar file: /tmp/sqoop-hdfs/compile/f068e5d884f3929b6415cd8318085fea/vjbkeufwekdfas.jar

However, if I don't use the double quotation marks:
sqoop job --create vjbkeufwekdfas -- import --split-by Birthdate
--check-column Birthdate --hive-database chinacloud --hive-table hive_vjbkeufwekdfas --target-dir /tmp/vjbkeufwekdfas --incremental lastmodified --username GA_TESTER1 --password 123456 --connect jdbc:oracle:thin:#172.16.50.12:1521:ORCL --query "SELECT \"Name\",\"ID\",\"Birthdate\" FROM GA_TESTER1.gmy_table1 where \$CONDITIONS" --m 1 --class-name vjbkeufwekdfas --hive-import

The oracle gonna throw error, because the field has some lower-case letters：

I am so confused, any help?
I think, It could be a case-sensitivity problem. In general, tables and columns are not case sensitive, but they will be if you use with quotation marks.
Try the following,
sqoop job --create vjbkeufwekdfas -- import --split-by Birthdate
--check-column Birthdate --hive-database chinacloud --hive-table hive_vjbkeufwekdfas --target-dir /tmp/vjbkeufwekdfas --incremental lastmodified --username GA_TESTER1 --password 123456 --connect jdbc:oracle:thin:#172.16.50.12:1521:ORCL --query "SELECT \”NAME\”,\”ID\”,\”BIRTHDATE\” FROM GA_TESTER1.gmy_table1 where \$CONDITIONS" --m 1 --class-name vjbkeufwekdfas --hive-import
--fields-terminated-by '^X' --hive-drop-import-delims --null-non-string '' --
If it’s still not working, Try the ‘eval’ first and make sure the query is working fine
sqoop eval --connect jdbc:oracle:thin:#172.16.50.12:1521:ORCL --query "SELECT \”NAME\”,\”ID\”,\”BIRTHDATE\” FROM GA_TESTER1.gmy_table1 where \$CONDITIONS"
As per sqoop user guide
" While the Hadoop generic arguments must precede any import arguments, you can type the import arguments in any order with respect to one another."
Please check your argument sequence.
Please try below..
sqoop job --create vjbkeufwekdfas \
-- import \
--connect jdbc:oracle:thin:#172.16.50.12:1521:ORCL \
--username GA_TESTER1 \
--password 123456 \
--query "SELECT \"Name\",\"ID\",\"Birthdate\" FROM GA_TESTER1.gmy_table1 where \$CONDITIONS" \
--target-dir /tmp/vjbkeufwekdfas \
--split-by "Birthdate" \
--check-column "Birthdate" \
--incremental lastmodified \
--hive-import \
--hive-database chinacloud \
--hive-table hive_vjbkeufwekdfas \
--class-name vjbkeufwekdfas \
--fields-terminated-by '^X' \
--hive-drop-import-delims \
--null-non-string '' \
--null-string '' \
--m 1
use
--append \
--last-value "0001-01-01 01:01:01" \
I want to export STRING data from Hive to CLOB in Oracle.

As a workaround I used --map-column-java tag.
I mapped Clob column (named col_clob) to String in Java.
Added below code in above command:
--map-column-java tag col_clob=String
I am trying to import a table data from Redshift to HDFS (using Parquet format) and facing the error shown below:

--password "password" --query "SELECT * FROM mobile_og.pages WHERE \$CONDITIONS" --split-by anonymous_id --target-dir
/user/huser/pq_mobile_og_pages_2 --as-parquetfile.
It works fine when --as-parquetfile option is removed from the above command line query.
It is confirmed to be a bug SQOOP-2571.
If you want to import all data of a table, then you can eventually run such a command:
sqoop import --driver "com.amazon.redshift.jdbc41.Driver" \
--connect "jdbc:postgresql://:5439/events" \
--username "username" --password "password" \
--table mobile_og.pages \
--split-by anonymous_id \
--target-dir /user/huser/pq_mobile_og_pages_2 \
--as-parquetfile
And --where is also an useful parameter. Check the user manual.
