Custom partitioner

[Hafiz Mujadid <ha...@gmail.com>]

Hi

I have csv data in which i have a column of date time. I want to partition
my data in 12 partitions with each partition containing data of one month
only. I am not getting how to write such partitioner and how to use that
partitioner to read write data.  

Kindly help me in this regard.

Thanks

You can write subclass of Partitioner whose getPartition() returns
partition number corresponding to the given key.

Take a look at
core/src/main/scala/org/apache/spark/api/python/PythonPartitioner.scala for
an example.

Cheers
