sqoop incremental load failed with timestamp

divakarreddy_a — Wed, 22 Jun 2016 11:22:14 GMT

Hi,

I'm trying to run sqoop incremental imports from Teradata to HDFS but running into issues with time stamp.

my sqoop command:

sqoop import \

--connect jdbc:teradata://PH/DATABASE=hadoop,CHARSET=UTF8 \

--driver "com.teradata.jdbc.TeraDriver" \

--username hadoop \

--password Hadoop \

--table item \

--target-dir /diva/item_text \

--m 1 \

--fields-terminated-by '|' \

--incremental append -check-column dw_modify_ts --last-value '2013-01-01 02:00:00'

Error Message:

Error: java.io.IOException: SQLException in nextKeyValue

Caused by: java.sql.SQLException: [Teradata Database] [TeraJDBC 15.00.00.20] [Error 6760] [SQLState HY000] Invalid timestamp.

Log Message:

-----------------------------------

16/06/22 04:13:43 INFO tool.ImportTool: Incremental import based on column dw_modify_ts

16/06/22 04:13:43 INFO tool.ImportTool: Lower bound value: '2013-01-01 02:00:00'

16/06/22 04:13:43 INFO tool.ImportTool: Upper bound value: '2013-07-10 22:56:01.0'

16/06/22 04:13:43 INFO mapreduce.ImportJobBase: Beginning import of e2_item_category_text

Here as per above log sqoop giving milliseconds as well in Upper bound Value "'2013-07-10 22:56:01.0'?

I'm suspecting that this milliseconds format having an issue while importing data from Teradata.

Can you suggest me if you have any idea?

I'm thinking that the value of '0000-00-00 00:00:00' date is stored in our db but can't be handled by the driver.

Changed incremental to lastmodified "--incremental lastmodified" in sqoop script but still getting an error.

16/06/22 04:35:16 ERROR manager.SqlManager: SQL exception accessing current timestamp: java.sql.SQLException: [Teradata Database] [TeraJDBC 15.00.00.20] [Error 3706] [SQLState 42000] Syntax error: expected something between '(' and ')'. java.sql.SQLException: [Teradata Database] [TeraJDBC 15.00.00.20] [Error 3706] [SQLState 42000] Syntax error: expected something between '(' and ')'.

below script is running fine, then no issues with timestamp running scripts in Teradata, it seems issue with incremental or Upper value milliseconds format.

sqoop import \

--connect jdbc:teradata://abc/DATABASE=hadoop,CHARSET=UTF8 \

--driver "com.teradata.jdbc.TeraDriver" \

--username hadoop \

--password 00000 \

--query "select * from text where dw_load_ts >='2016-01-01 00:00:00' AND \$CONDITIONS" \

--target-dir /diva/text \

--m 1

There appears to be a bug in Sqoop for lastmodified import from Teradata. Regarding "append" import can you try to use an INT column as "check-column".

Thanks Predrag.

it's working for "append" and INT column as "check-column"

another quick question:

Do we need to pass "--last -value" every time based on previous "Upper bound value:####"?

Glad to hear it worked! Regarding "last-value" it's the best to create a Sqoop job, for example

sqoop job --create myjob -- import --connect jdbc:teradata ...

and then just execute "sqoop job --exec myjob" every time. Sqoop will memorize last-value in its internal storage. For a "lastmodified" example see the answer to this post.
