I have a Hive table like below..I would like have the first column to be a constant value (Its not coming in the XML file). if I hardcode the value, its not being displayed when I do a select on the table... what am I doing wrong? I tried using the concatenate operator also (with dummy xpath and adding the string)...still no luck ...any help is appreciated..
`
CREATE EXTERNAL TABLE IF NOT EXISTS raw_RMS_20170629(
SourceSystem STRING,
Account STRING,
Action STRING,
AllocationType STRING,
AlternativeTradeId STRING,
...
...
ROW FORMAT SERDE 'com.ibm.spss.hive.serde2.xml.XmlSerDe'
WITH SERDEPROPERTIES (
"column.xpath.SourceSystem"="RMS",
"column.xpath.Account"="Trade/Account/text()",
"column.xpath.Action"="Trade/Action/text()",
"column.xpath.AllocationType"="Trade/AllocationType/text()",
...
...
Sample Data below. The external table is created dynamically everytime oozie workflow runs and I would like to add a constant field (sourcesystem = RMS or.. GSS etc when I create the table)
