Chao Sun commented on HDFS-8631:
--------------------------------
Thanks [~surendrasingh] for taking a look.
bq. 1. "0" should be considered as a valid value for space quota.
The behavior in {{WebHdfsFileSystem}} is the same as in
[{{DFSClient}}|https://github.com/apache/hadoop/blob/trunk/hadoop-hdfs-project/hadoop-hdfs-client/src/main/java/org/apache/hadoop/hdfs/DFSClient.java#L2509]
which does not consider 0 as a valid value. In fact the
[QuotaAdminGuide|https://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-hdfs/HdfsQuotaAdminGuide.html]
also says that namespace quota should be a positive long.
bq. 2. Why FSOperations changes is required? Are you planning to implement this
API in HttpFSServer.
Good catch! I do intend to add the API for HttpFSServer but in a different
patch. Will remove here.
