Subject Re: S3 token times out during data frame "write.csv"
Date Sun, 28 Jan 2018 05:49:22 GMT
Hi,

There is definitely a parameter while creating temporary security
credential to mention the number of minutes those credentials will be
active. There is an upper limit ofcourse which is around 3 days in case I
remember correctly and the default, as you can see, is 30 mins.

Can you let me know:
1. how you are generating the credentials? (the exact code)
2. doing S3 writes from local network is super suboptimal anyway given the
network latency and cost associated with it. So why are you doing it?
3. when you are porting your code to EMR, do you still use accesskeys or do
you have to change your code?
4. Any particular reason why your partition value has "-" in it, therefore
I am trying to understand why is the partition value 2018-01-23 instead of
20180123? Are you considering the partition type to be String?
5. Have you heard of and tried using spot instances, the cost is so
ridiculously low at that point of time, that there is no need to be running
the code locally (I am expecting that since you can run the code locally,
therefore the EMR instance size and node type would be small)
6. Why are you not using Parquet format and using ORC instead? I think that
many more products use Parquet and only HIVE uses ORC format.

Regards,
Gourav Sengupta
