Number of partitions of IgniteRDD

[vijayendra bhati]

Hi,
Can anybody let me know the criteria on which number of partitions are decided 
for IgniteRDD ?From the IgniteRDD code, as per getPartitions() implementation 
it is dependent upon number of partitions of underlying cachebut I am not aware 
how the number of partitions of underlying cache is decided.
