Subject [jira] [Created] (HDFS-14724) Fix JDK7 compatibility in branch-2
Date Mon, 12 Aug 2019 16:43:00 GMT
Wei-Chiu Chuang created HDFS-14724:

             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.
