update specifc rows to DB using sqlContext

[sujeet jog]

Hi,

Is it possible to update certain columnr records  in DB  from spark,

for example i have 10 rows with 3 columns  which are read from Spark SQL,

i want to update specific column entries  and write back to DB, but since
RDD"s are immutable i believe this would be difficult, is there a
workaround.


Thanks,
Sujeet
