Hive custom inputfomat error.

[Manish]

I have created custom input format in java. Now I want to use that input
format when creating table in Hive. 

Here are my steps: 
1.    Created jar file of the program.
2.    Copied jar in /usr/lib/hadoop.
3.    Added the path in CLASSPATH.

now here is my code:

Create table hitdata_fnl
(
col_0  string,
col_1  string, 
col_2  string, 
col_3  string, 
col_4  string, 
col_5  string, 
col_6  string, 
col_7  string, 
col_8  string, 
col_9  string, 
col_10  string
)
ROW FORMAT DELIMITED FIELDS TERMINATED BY '\t' 
STORED AS INPUTFORMAT 'com.tgam.hadoop.mapreduce.inputfilerecordreader'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat';

Error : 
FAILED: Error in metadata: Class not found:
com.tgam.hadoop.mapreduce.inputfilerecordreader
FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.DDLTask

Please help on this error.

Thank You,
Manish.
