Hi
I have a json file that can be load by sqlcontext.jsonfile into a
table. but this table is not partitioned.
Then I wish to transform this table into a partitioned table say on
field “date” etc. what will be the best approaching to do this? seems in hive
this is usually done by load data into a dedicated partition directly. but if I
don’t want to select data out by a specific partition then insert it with each
partition field value. How should I do it in a quick way? And how to do it in
Spark sql?
