Subject [jira] [Updated] (HDFS-7287) The OfflineImageViewer (OIV) can output invalid XML depending on the filename
Date Wed, 29 Oct 2014 15:27:34 GMT

     [ https://issues.apache.org/jira/browse/HDFS-7287?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ravi Prakash updated HDFS-7287:
-------------------------------
    Status: Open  (was: Patch Available)

Aah! I found it. The test TestOfflineImageViewer was failing because the character '<'
is being passed as is. Here's the XML output generated for the test testPBImageXmlWriter()
when a directory named "/dirContainingInvalidXMLChar\u0000<-here" was in the fsimage. I'll
file a follow up JIRA to fix that.

> If the filename contains a character which is invalid in XML, TextWriterImageVisitor.write()
or PBImageXmlWriter.o() prints out the string unescaped. For us this was the character 0x0
