1.) While importing or exporting from sqoop to hive, do you have to handle NULL? Do they specify anything about NULL handling in the question?
– They don’t specify obvious things like , delimiter used the hdfs files, you can always find it.
– About NULL handling they should give you instruction on what to do else by default people will not use it as I didn’t use it.
2.) If they don’t mention anything about rounding price to 2 decimal, have you did it or not?Are we suppose to do it or leave it as it is?
– Cloudera gives sample output so that one can produce the same result set. They had given me sample output to produce the data where I didn’t have to round to 2 decimal places. (advice) Don’t do it if they don’t ask.
Let me know if there are any doubts.
