RE: Loading data with Sqoop
Hi Roberto,
How the tool is working?
Directly loading data from RDBMS to Phoenix using Sqoop? or loading after bulk file is dumped into HDFS?
Thanks & Regards
Job M Thomas

Hi Roberto,
How are you constructing the composite row key and returning the Put from the transformer . Also, can you please throw some light on how you perform a look up on the data types of the columns within the transformer.
Regards
Ravi

Hi James,
I have extended the PutTransformer I've implemented and now it's loading data into tables with composite primary key.
Another scenario I'm still working on is to identify if the table is salted, and load the data accordingly.
Can you think in any other scenario?
Roberto.

Hi Roberto,
Yes, thank you very much for asking - there's definitely interest. Does it handle the case with a table that has a composite primary key definition?
Thanks,

Hi there,
I came across the challenge of loading data from a RDBMS into a Phoenix table using Sqoop, but that did not work well as Sqoop by default converts all data types to string.
I came up with a solution to write a PutTransformer that maps the jdbc data types to the Phoenix native data types.
Is there any interest to include this feature to the project? If so, I can contribute.
Roberto.

Any updates on this one? It'd be very nice to have Sqoop integration.
Thanks,
James

Hi Job,
The tool is basically an implementation of PutTransformer class. When the
Sqoop job is executed you can provide the jar file and the class using -D
option.
And to answer your second question, it will load the data directly to the
HBase table.
Roberto.
