Hi How does hive interpret the complex datatpes (my own class) in the sequence file, say i have my own complex datatype (my own class) as the value written in the Sequence File. How do I make Hive read this, read it as corresponding columns.
For Ex. I have this sequence file writeen as hadoop writable on HDFS with records 100 One, two, buckle my shoe 99 Three, four, shut the door 98 Five, six, pick up sticks Now in Hive, i create a external table, 1.create external table seqExampleMap (number map<STRING,STRING>) row format delimited fields terminated by ' ' STORED AS SEQUENCEFILE location '/user/hiveFiles/'; How do I say that "One" is the key and "two, buckle my shoe" is the value in the map number created above? Please suggest Thanks Ranjitha. ::DISCLAIMER:: ---------------------------------------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
