Subject Re: Import data to HDFS using Sqoop2
Date Wed, 04 Sep 2013 01:34:33 GMT
However, with Sqoop 1.4.4, all schema and table names are lower-case, and
it is successful to make import.

As a result, I am not sure if case sensitivity will be a problem in Sqoop 2.

*This is the connection I created:*
1 connection(s) to show:
Connection with id 1 and name ds_msg_log (Created 9/2/13 10:54 AM, Updated
9/3/13 6:35 PM)
Using Connector id 1
  Connection configuration
    JDBC Driver Class: org.postgresql.Driver
    JDBC Connection String: jdbc:postgresql://MY_IP:MY_PORT/invoice
    Username: hadoop
    Password:
    JDBC Connection Properties:
  Security related configuration options
    Max connections: 123

*This is the job I created:*
Job with id 3 and name ds_msg_log (Created 9/2/13 11:37 AM, Updated 9/3/13
5:57 PM)
Using Connection id 1 and Connector id 1
  Database configuration
    Schema name: invoice
    Table name: ds_msg_log
    Table SQL statement:
    Table column names:
    Partition column name:
    Boundary query:
  Output configuration
    Storage type: HDFS
    Output format: TEXT_FILE
    Output directory: /user/root/ds_msg_log_sqoop2

*The command I use to start this job is:*
submission start --jid 3
