> Hey All,
> I wanted to add a notion of skipping invalid rows for PhoenixHbaseStorage similar to
how the CSVBulkLoad tool has an option of ignoring the bad rows.I did some work on the apache
pig code that allows Storers to have a notion of Customizable/Configurable Errors PIG-4704.
> I wanted to plug this behavior for PhoenixHbaseStorage and propose certain changes for
the same.
> Current Behavior/Problem:
> PhoenixRecordWriter makes use of executeBatch() to process rows once batch size is reached.
If there are any client side validation/syntactical errors like data not fitting the column
size, executeBatch() throws an exception and there is no-way to retrieve the valid rows from
the batch and retry them. We discard the whole batch or fail the job without errorhandling.
> With auto commit set to false execute() also servers the purpose of not making any rpc
calls  but does a bunch of validation client side and adds it to the client cache of mutation.
> On conn.commit() we make a rpc call.
> Proposed Change
> To be able to use Configurable ErrorHandling and ignore only the failed records instead
of discarding the whole batch I want to propose changing the behavior in PhoenixRecordWriter
from execute to executeBatch() or having a configuration to toggle between the 2 behaviors
