If I have a big amount of data database which are to be parsed into impala and something goes wrong in the process of parsing, the parsing will start from the zero or I can do something in order to start again from the part which crashed the process?
I am not into this now , I just want to be prepared and find the most efficient way. The data will reach the layer with HDFS. I was just curious if it is better to do it with Talend components or with sqoop in case that something will go wrong in the parsing. I dont want to start from the zero everytime.
