Another processor that may be of interest to you is the QueryDatabaseTable processor, which
has just been released in 0.6.0. This provides incremental load capabilities similar to sqoop.

If you’re looking for the schema type functionality, bear in mind that the ExecuteSQL (and
new Query processor) preserve schema with Avro.

Sqoop also allows import to HBase, which you can do with PutHBaseJson (use the ConvertAvroToJson
processor to feed this).

Distributed partitoned queries isn’t in there yet, but I believe is on the way, so sqoop
may have the edge for that use case today.

Granted, NiFi doesn’t have much by way of HCatalog integration at the moment, but most of
the functionality you’ll find in Sqoop is in NiFi. Unless you are looking to move terabytes
at a time, then NiFi should be able to handle most of what you would use sqoop for, so it
would be very interesting to hear more detail on your use case, and why you needed sqoop on
top of NiFi.

Hi,

Yes, In my case i have created the Custom processor with Sqoop API which accommodates complete
functionality of sqoop.
As per you concern we have able to move the data only from HDFS to SQl or Vice versa, But
sqoop having more functionality which we can achieve it by Sqoop.RunTool() in org.apache.sqoop.sqoop.
The Sqoop Java client will works well and Implement that API into new Sqoop NIFI processor
Doesn't work!

Hi,
If you could explain exactly what you are trying to achieve I.e. What part of the data pipeline
you are looking to use NiFi for and where you wish to retain Sqoop I could perhaps have a
more informed input (although I have only been using NiFi myself for a few weeks). Sqoop obviously
can move the data from RDBM systems through to HDFS (and vice versa) as can NiFi, not sure
why you would want the mix (or at least I can’t see it from the description you have provided
thus far).
I have limited knowledge of Sqoop, but either way, I am sure you could ‘drive’ Sqoop from
a custom NiFi processor if you so choose, and you can ‘drive’ NiFi externally (using the
REST api) - if Sqoop can consume it.

Hi Conrad,

Thanks for Quick Response.

Yeah.Combination of Execute SQL and Put HDFS works well instead of Sqoop.But is there any
possible to use Sqoop(client) to do like this?

Hi,
Why use sqoop at all? Use a combination of ExecuteSQL [1] and PutHDFS [2].
I have just replace the use of Flume using a combination of ListenSyslog and PutHDFS which
I guess is a similar architectural pattern.

Hi,

I am new to nifi.

       I have to know that  "Is there is any Support for Sqoop with help of NIFI Processors?."

And in which way to done the following case with help of Sqoop.

    Move data from oracle,SqlServer,MySql into HDFS and vice versa.


Thanks,
