   Any update on this issue? I am facing this issue in one of my project with parquet format and its pissing me off. I don't want to alter the dataset by replacing space with `_` OR removing it altogether.

> Add the ability to quote identifiers for columns in a table. This would allow column names to contain arbitrary characters such as spaces. Hive supports these types of identifiers using backquotes. For example,
> create table parquet_table (`Session Token` string) stored as parquetfile;
> However, attempting to insert a new row into this table results in an error.
> insert into parquet_table values ('1234-45')
> org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.IllegalArgumentException: field ended by ';': expected ';' but got 'token' at line 1:   optional string Session Token
> I would suggest using backquotes in Parquet as well.
