             Summary: 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


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.
