ASF GitHub Bot commented on HDFS-16734: --------------------------------------- ZanderXu opened a new pull request, #4763: URL: https://github.com/apache/hadoop/pull/4763 ### Description of PR Suppose there are some mount points as bellows in RBF without default namespace. |Source Path|NameSpace|Destination Path | |:----:|:----:|:----:| |/a/b|ns0|/a/b| |/a/b/c|ns0|/a/b/c| |/a/b/c/d|ns1|/a/b/c/d| Suppose there a file /a/b/c/file1 with 10MB data in ns0 and a file /a/b/c/d/file2 with 20MB data in ns1. There are bugs during handling some cases: |Case Number|Case|Current Result|Expected Result| |:---:|:---:|:---:|:---:| |1|getContentSummary('/a')|Throw RouterResolveException |2files and 30MB data| |2|getContentSummary('/a/b')|3files and 40MB data|2files and 30MB data| Bugs for these cases: - Case1: If can't find any locations for the path, RBF should try to do it with sub mount points. - Case2: RBF shouldn't repeatedly get content summary from one same namespace with same ancestors path, such as from ns0 with /a/b and from ns0 with /a/b/c. > RBF: fix some bugs when handling getContentSummary RPC > ------------------------------------------------------ > > Key: HDFS-16734 > URL: https://issues.apache.org/jira/browse/HDFS-16734 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: ZanderXu > Assignee: ZanderXu > Priority: Major > > Suppose there are some mount points as bellows in RBF without default > namespace. > ||Source Path||NameSpace||Destination Path || > |/a/b|ns0|/a/b| > |/a/b/c|ns0|/a/b/c| > |/a/b/c/d|ns1|/a/b/c/d| > Suppose there a file /a/b/c/file1 with 10MB data in ns0 and a file > /a/b/c/d/file2 with 20MB data in ns1. > There are bugs during handling some cases: > ||Case Number||Case||Current Result||Expected Result|| > |1|getContentSummary('/a')|Throw RouterResolveException |2files and 30MB data| > |2|getContentSummary('/a/b')|2files and 40MB data|3files and 40MB data| > Bugs for these cases: > Case1: If can't find any locations for the path, RBF should try to do it > with sub mount points. > Case2: RBF shouldn't repeatedly get content summary from one same namespace > with same ancestors path, such as from ns0 with /a/b and from ns0 with /a/b/c. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
