[jira] [Updated] (SQOOP-3001) Import from Mysql broken with "Caused
by: java.lang.ClassCastException: java.lang.Integer cannot be cast to
java.math.BigDecimal"
[ https://issues.apache.org/jira/browse/SQOOP-3001?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Sergey Svinarchuk updated SQOOP-3001:
-------------------------------------
Description:
After patch from SQOOP-2244, Sqoop incorrect get type for column.
Example for select with automatically escape column names:
{code}
mysql> create table test (id int);
Query OK, 0 rows affected (0.01 sec)
mysql> insert into test value (1);
Query OK, 1 row affected (0.04 sec)
mysql> insert into test value (9);
Query OK, 1 row affected (0.01 sec)
mysql> select min("id"), max("id") from test;
+-----------+-----------+
| min("id") | max("id") |
+-----------+-----------+
| id | id |
+-----------+-----------+
1 row in set (0.00 sec)
{code}
But real results must be:
{code}
mysql> select min(id), max(id) from test;
+---------+---------+
| min(id) | max(id) |
+---------+---------+
| 1 | 9 |
+---------+---------+
1 row in set (0.00 sec)
{code}
So when we use auto escape, Sqoop getting String value for int column in Mysql
was:
