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. > GetContentSummary API and its namenode implementaion for Storage Type > Quota/Usage > --------------------------------------------------------------------------------- > > Key: HDFS-7824 > URL: https://issues.apache.org/jira/browse/HDFS-7824 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: datanode, namenode > Reporter: Xiaoyu Yao > Assignee: Xiaoyu Yao > Attachments: HDFS-7824.00.patch, HDFS-7824.01.patch, > HDFS-7824.02.patch, HDFS-7824.03.patch > > > This JIRA is opened to provide API support of GetContentSummary with storage > type quota and usage information.
