Some doubts about ORC:


*1- hive.exec.orc.default.buffer.size* is used for read or write?

*2- orc.stripe.size* is compressed or uncompresed?

*3- orc.stripe.size* must be multiple of HDFS block size?

4- For read ORC file , the numbers of mappers depends onr HDFS blocks or
Stripe number?

*5- hive.exec.orc.split.strategy *is used for read?
