NameNodeMetrics should use MetricsTimeVaryingLong
--------------------------------------------------
Key: HDFS-1339
URL: https://issues.apache.org/jira/browse/HDFS-1339
Project: Hadoop HDFS
Issue Type: Bug
Components: name-node
Reporter: Scott Chen
Assignee: Scott Chen
Priority: Minor
NameNodeMetrics uses MetricsTimeVaryingInt. We see that FileInfoOps and
GetBlockLocations overflow in our cluster.
Using MetricsTimeVaryingLong will easily solve this problem.
