Sqoop “import-all-tables” unable to import all tables

问题


this is the sqoop command which I am using to import data from SQL Server to Hive
sqoop-import-all-tables --connect "jdbc:sqlserver://ip.ip.ip.ip\MIGERATIONSERVER;port=1433;username=sa;password=blablaq;database=sqlserverdb" --create-hive-table --hive-import --hive-database hivemtdb
The problem is that sqlserverdb has about 100 tables but when i issue this command it is just importing 6 or 7 random tables to hive. This behavior is really strange for me. I am unable to find where I am doing mistake.

First of all import-all-tables will run import table for all the tables.

If you does not define, number of mapper in the job, Sqoop will pick by default 4 mappers. So, it needs table to have primary key or you specify --split-by column name.

If this is the case, you will see error like:

ERROR tool.ImportAllTablesTool: Error during import: No primary key could be found for table test. Please specify one with --split-by or perform a sequential import with '-m 1'.

So you can use 1 mapper which will make your import process slow.

Better way is to add --autoreset-to-one-mapper, it will import tables with primary key with the number of mappers mentioned in the command and it will automatically use 1 mapper for the tables without primary key.


Coming to your problem,

sqoop import failed for table DadChMasConDig.

I don't know why it is not logged on console.

In importing this table there could be exception like

Encountered IOException running import job: java.io.IOException: Hive does not support the SQL type for column <somecolumn>

For example, varbinary is not supported.

If you import data only in HDFS, it should not be a problem. You can try:

sqoop-import-all-tables --connect "jdbc:sqlserver://ip.ip.ip.ip\MIGERATIONSERVER;port=1433;username=sa;password=blablaq;database=sqlserverdb"

I had the same issue and the following worked for me. Though typically --create-hive-table and --hive-overwrite don't go together and doesn't make sense together. But no other combination worked and each time only 3 of 10 or a fraction of tables were getting imported

 sqoop import-all-tables \
       --connect jdbc:mysql://<mysql-url>/my_database \
       --username sql_user \
       --password sql_pwd \
       --hive-import \
       --hive-database test_hive \
       --hive-overwrite \
       --create-hive-table \
       --warehouse-dir /apps/hive/warehouse/test_hive.db \
       -m 1
