Hello, I am struggling to make it work, what is a really required feature.
I have a process that daily generates new data, this data needs to be
pushed to a table in Oracle, the table might already have same data from
previous loads. I need to avoid duplicating data on it. Pretty common
scenario right? =)
I am using sqoop export for this, no special arguments, just columns,
fields-terminated-by, table and db connection, plus the argument
"update-mode allowinsert".
Now, when I also include the argument "update-key" with a comma separated
list of fields (which is the same for arg columns) I get the following
oracle driver error:

I'm using Sqoop 1.4.3 with hadoop1, also tried 1.4.4 with same result. I
have the standard Oracle JDBC driver 6 with Java 7.
I went through all the documentation, Sqoop user guide says this is
supported for built-in connector which I understand I am using.
Here is the full command:
$sqoopExecutable export \
--outdir $outdir \
--connect $connectionString --table $table_client --username $dbUser
--password $dbUserPasswd \
--columns CLIENT_ID,EXP_ID,BUCKET_ID --update-key
CLIENT_ID,EXP_ID,BUCKET_ID \
--fields-terminated-by '\t' --update-mode allowinsert \
--export-dir $dataSource_client > $sqoopLog 2>&1
Can someone please shed some light on this?
Thank you in advance.
Leo
