> Key: HDFS-10459

> Project: Hadoop HDFS

> The computation works on threshold = 1, but not on threshold < 1. I propose
> making blockThreshold equal to the ceiling of total*threshold. Since we need
> to be >= blockThreshold to get out of safe mode, >14.9 is the same as =15,
> since blocks work in integer values.
