Hi all, This is my first post here. I have an issue trying to map a JSON field starting with a hash (#) to a Hive column using the (simplified) statement below : CREATE EXTERNAL TABLE foobar_table ( foobar STRING ) ROW FORMAT SERDE 'org.apache.hive.hcatalog.data.JsonSerDe' WITH SERDEPROPERTIES ( 'mapping.foobar' = '#foobar' ) LOCATION '/data/foobar'; Using the following JSON file below: {"#foobar":"some_value"} There are no issues when the special character is removed, but this is no solution in the real-world scenario. Is the fact the mapping isn't working a bug in the code, or am I using the wrong (version of) JsonSerDe. I'm using HDP-2.5.0.0 Hopefully someone can supply with an answer other then renaming the JSON field. Thanks in advance.. ... View more
