Veena Basavaraj commented on SQOOP-1801:
----------------------------------------

Again, there is not much work in this ticket, It will mainly document how config validation
can happen and provide probable examples connectors can use to provide inputs and validation
for the inputs in the config classes for delta read and delta writes

> The configs will mainly have the operators, columns and values
> 1. Required/ Optional validation
> operators (Required, or we default to > ) , column (Required)  and values ( optional)
and the las-value in the from config will be used
> 2. Enum of supported operators and its semantics and check if the operator is valid
> Supported operators ( < , >, LIKE, IN BETWEEN...) to begin with 
> 3. Validate if the column exists in the data source.
> 4. Validate that the corresponding connectors support the incremental.
> Few more are possible depending on how much feedback we want to give in the early stages...
