Block size 1GB, 2GB

Sudhir Babu Pothineni
Hi, I am trying to use larger block size like 1GB, 2GB. In our case the files are 5GB to 12GB size and we process whole file per mapper, is there any side effects to using larger block size like 1GB, 2GB? Like HDFS stability when doing replication?

Thanks
Sudhir
