Michael Styles created PARQUET-677:
--------------------------------------
Summary: Quoted identifiers in column names
Key: PARQUET-677
URL: https://issues.apache.org/jira/browse/PARQUET-677
Project: Parquet
Issue Type: Improvement
Components: parquet-mr
Reporter: Michael Styles
Priority: Minor
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.
