Attachment: HDFS-12778-HDFS-9806.001.patch
Attaching a patch where {{getBlockLocations}} on a PROVIDED file will return
the default number of replicas configured ({{dfs.replication}}). More
precisely, the number of locations returned for PROVIDED files = (number of
local replicas) + min({{dfs.replication}} - (number of local replicas), number
of datanodes configured with PROVIDED storage type).
The patch also fixes the affected unit tests in
{{TestNameNodeProvidedImplementation}}.
