Xiaoyu Yao commented on HDFS-7824:
----------------------------------
The javac warning is from TestCount.MockContentSummary which extends
ContentSummary with default constructor that has been deprecated by the new
ContentSummary.Builder class.
{code}
> [WARNING]
> /home/jenkins/jenkins-slave/workspace/PreCommit-HDFS-Build/hadoop-common-project/hadoop-common/src/test/java/org/apache/hadoop/fs/shell/TestCount.java:[318,32]
> [deprecation] ContentSummary() in ContentSummary has been deprecated
{code}
There are two approaches that we can fix this:
1) Suppress the warning for TestCount.MockContentSummary#MockContentSumary()
{code}
static class MockContentSummary extends ContentSummary {
@SuppressWarnings("deprecation")
// suppress warning on the usage of deprecated ContentSummary constructor
public MockContentSummary() {
}
{code}
2) Change MockContentSummary from inheritance to composition and provide mocks
for all the ContentSummary methods.
Considering this is for the single test only and amount of changes for 2), I
would prefer 1). Let me know if you have other ideas on fixing this.
