> Key: HIVE-4618
> URL: https://issues.apache.org/jira/browse/HIVE-4618
> Project: Hive
> Issue Type: Bug
> Components: CLI
> Affects Versions: 0.10.0
> Environment: CDH4.2
> Hive 0.10
> Reporter: Johndee Burks

> 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'

> hive> desc formatted j1;
> …shortened to save space
