Hi Sanjay Thank you for the quick response.
I got the input format part from the link that u sent. But in order to read that table in Hive, i need to specify the SerDe, where exactly do I specify this class file. Is it something like, create table seq10 (key STRING, value STRING) ROW FORMAT SERDE 'com.org.SequenceFileKeyRecordReader' STORED AS INPUTFORMAT 'com.org.SequenceFileKeyInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat' LOCATION <hdfs path>; Is this the right approach where i specify the input file format and write a custom serDe too..? Please correct me if I am wrong Thanks Ranjitha.
