--------------------------------------
Summary: Fix JDK7 compatibility in branch-2
Key: HDFS-14724
URL: https://issues.apache.org/jira/browse/HDFS-14724
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 2.10.0
Reporter: Wei-Chiu Chuang
With the feature Consistent Read from Standby now in branch-2, I found it
breaks the build when building with JDK7, because it uses
java.util.concurrent.atomic.LongAccumulator which is only in JDK8 and above.
We should figure out if we want to fix it, or give up JDK7 compatibility.
