Subject [jira] [Commented] (HDFS-1575) viewing block from web UI broken
Date Wed, 18 May 2011 22:12:47 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1575?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13035784#comment-13035784
] 

Todd Lipcon commented on HDFS-1575:
-----------------------------------

Since these changes are just in the java, it seems we could have some true unit tests for
it?
Also, when concatenating "val" in the getUrlParam functions, shouldn't it be encoded?

> DatanodeJspHelper seems to expect the file path to be in the "path info" of the HttpRequest,
rather than in a parameter. I see the following exception when visiting the URL {{http://localhost.localdomain:50075/browseBlock.jsp?blockId=5006108823351810567&blockSize=20&genstamp=1001&filename=%2Fuser%2Ftodd%2Fissue&datanodePort=50010&namenodeInfoPort=50070}}
