> When including a "fields terminated by" in the create statement. If the delimiter is
preceded by a \001, hive turns this into \u0001 which is correct. However it then gives you
a ddl that does not work because the parser changes the \u0001 into u0001. 
> Example: 
> hive> create table j1 (a string) row format delimited fields terminated by '\001';
> hive> show create table j1;
> CREATE  TABLE j1(
>   a string)
> ROW FORMAT DELIMITED
>   FIELDS TERMINATED BY '\u0001'
> STORED AS INPUTFORMAT
>   'org.apache.hadoop.mapred.TextInputFormat'
> OUTPUTFORMAT
>   'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
> LOCATION
>   'hdfs://forza-1.cloud.rtp.cloudera.com:8020/user/hive/warehouse/j1'
> TBLPROPERTIES (
>   'transient_lastDdlTime'='1369664999')
> hive> desc formatted j1;
> …shortened to save space
> Storage Desc Params:
> 	field.delim         	\u0001
> 	serialization.format	\u0001
> hive> drop table j1;
> hive> CREATE  TABLE j1(
>     >   a string)
>     > ROW FORMAT DELIMITED
>     >   FIELDS TERMINATED BY '\u0001'
>     > STORED AS INPUTFORMAT
>     >   'org.apache.hadoop.mapred.TextInputFormat'
>     > OUTPUTFORMAT
>     >   'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
>     > LOCATION
>     >   'hdfs://forza-1.cloud.rtp.cloudera.com:8020/user/hive/warehouse/j1'
>     > TBLPROPERTIES (
