My source hdfs directory has 24 million records and when I do a sqoop export to Postgres table, it somehow creates duplicate records. I have set the number of mappers as 24. There are 12 blocks in the source location.
Any idea why the sqoop is creating duplicates?

I would like to know which one is better and any reason behind the same.
Note: My current utility is able to pull data using sqoop into HDFS , Create Hive staging table and archive external table.
Informatica is the ETL tool used in the organization.

I have worked on sqoop to extract data and found RDBMS gel up with HDFS via sqoop. However, no clear direction found to extract data from NoSQL DB with sqoop to dump it over HDFS for big chunk of data processing? Please share your suggestions and investigations.
I have extracted static information and data transactions from MySQL. Simply, used sqoop to store data in HDFS and processed the data. Now, I have some live transactions of 1million unique emailIDs per day which data modelled into MongoDB. I need to move data from mongoDB to HDFS for processing/ETL. How can I achieve this goal using Sqoop. I know I can schedule my task but what should be the best approach to take out data from mongoDB via sqoop.

I am trying to run the following query.
sqoop import --connect jdbc:mysql://IP:3306/database_name --table clients --target-dir /data/clients --username root --password-file /sqoop.password -m 1
sqoop.password is a file which is kept on HDFS in path /sqoop.password with permission 400.
It is giving me an error
Access denied for user 'root'@'IP' (using password: YES)
Can anyone provide solution for this?
