I'm trying to migrate a part of our current hadoop jobs from normal mapreduce
jobs to hive,
Previously the data was stored in sequencefiles with the keys containing
valueable data!
However if I load the data into a table I loose that key data (or at least I
can't access it with hive), I want to somehow use the key from the sequence
file in hive.
I know this has come up before since I can find some hints of people needing it
but I can't seem to find a working solution and since I'm not very good with
java I really can't get it done myself :(.
Does anyone have a snippet of something like this working?
I get errors like;
../hive/mapred/CustomSeqRecordReader.java:14: cannot find symbol
[javac] symbol : constructor SequenceFileRecordReader()
[javac] location: class
org.apache.hadoop.mapred.SequenceFileRecordReader<K,V>
[javac] public class CustomSeqRecordReader<K, V> extends
SequenceFileRecordReader<K, V> implements RecordReader<K, V> {
Hope some1 has a snippet or can help me out, would really love to be able to
switch part of our jobs to hive,
