Subject [jira] [Created] (HIVE-2685) Unable to query Hive table defined with custom ROW FORMAT remotely using JDBC

Unable to query Hive table defined with custom ROW FORMAT remotely using JDBC
-----------------------------------------------------------------------------

                 Key: HIVE-2685
                 URL: https://issues.apache.org/jira/browse/HIVE-2685
             Project: Hive
          Issue Type: Bug
          Components: JDBC
    Affects Versions: 0.7.1
         Environment: Cloudera VM for Linux Red Hat
            Reporter: Bobo Vava


Created table using custom format as follows :

create  table if not exists FILE_HDFS_TO_HIVE_CUSTOM_NO_STAGE_TGT
(
	ID	STRING,
	NAME	STRING,
	DESCR	STRING
)

ROW FORMAT SERDE 'org.apache.hadoop.hive.contrib.serde2.RegexSerDe'
WITH SERDEPROPERTIES (
  "input.regex" = "(.{3})(.{5})(.{9})",
  "output.format.string" = "%1$s %2$s %3$s"
)
STORED AS TEXTFILE

and loaded some data into it.

Now I am trying to query the table from a remote host using JDBC from a java program.
All the Hive JDBC jars are included in the classpath and I am able to execute run all kinds

of DDL and DML statements except for this one.
Additionally I use add jar just before executing the query :

add jar /ade/bosimova_bobo_odi/odi/odiqa/automation/qa_scripts/knowledge_modules/sql/hive_cert/drivers/hive-contrib-0.7.1-cdh3u2.jar
0

select * from file_hdfs_to_hive_custom_no_stage_tgt order by id
Query returned non-zero code: 9, cause: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.MapRedTask

java.lang.ClassNotFoundException: org.apache.hadoop.hive.contrib.serde2.RegexSerDe
