Storing and reading XML files in HIVE
Dear All, Request your help to guide how to store and read XML data in HIVE. while querying it should look as if we are having txt format file under HIVE (it is fine if we use view to parse the XML and show). Have gone through some sites but not able to figure out correctly.. few are mentioning that we need use some JAR's to achieve it... Thanks in advance, Rams

AFAIK, Hive doesn't provide XMLInputFormat , so you had to write it by yourself.
