Johndee Burks created HIVE-4618:
-----------------------------------
Summary: show create table creating unusable DDL when field
delimiter is \001
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
Priority: Minor
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 (
> 'transient_lastDdlTime'='1369664999');
hive> desc formatted j1;
…shortened to save space
Storage Desc Params:
field.delim u0001
serialization.format u0001
