HI Raja, As mentioned before, Spark creates the default number of partitions must be 8..Right? Then why only one partition has been cretaed in this example. Please help me on this?Thanks

Hi Raja, you got default partition as 1 because the size of the file is less than default partition size i.e., 128MB. is this statement true? default number of partitions are depending on maxPartitionBytes right? can you clarify this. TIA

rajunaik

I have uploaded a 6MB of file and reading that file.It should create 1 partition right bcoz for 128MB it will create a partition . But it was created 2 partitions. Could you please tell me the reason ???
