Subject Sqoop Merge failed
Date Fri, 28 Aug 2015 06:09:45 GMT
Hello Everyone,

I am trying to push incremental updates from Oracle to hdfs using sqoop import command with
Merge-key option and incremental mode as "lastmodified".
I have pasted below, my sqoop command and a part of repetitive exception from my logs.

--target-dir /user/$USER/PRF_USER_IDENTITY is the same location where I have data to be merged
with the latest incremental data.
Can't parse input data: 'BTCOM_MIGR_C'. This value exists in a column with VARCHAR2(20) NOT
NULL

I have framed the below command based on below link
https://mail-archives.apache.org/mod_mbox/sqoop-user/201505.mbox/%3CCAMZRiGzDe9sN8+Tb_MWtLcmb8+Q=agtURNa4Xkq7skYKzu+odQ@mail.gmail.com%3E



sqoop job --create prf_user_identity_delta -- import --connect jdbc:oracle:thin:@//xxx.xx.xx.xx:xxxx/xxxxxx
--username profileuserr6_0 --password-file /user/$USER/XXX/sqoop.password --table PRF_USER_IDENTITY
--incremental lastmodified --check-column LAST_UPDATED_DTIME --last-value "2015-08-21 14:42:42"
--merge-key PRF_USER_IDENTITY_ID --null-string '\\N' --null-non-string '\\N' --fields-terminated-by
, --input-null-string '\\N' --input-null-non-string '\\N' --input-fields-terminated-by , --target-dir
/user/$USER/PRF_USER_IDENTITY -m 1
