-Re: Example using Binary SerDe
Hans Uhlig 2012-01-23, 03:28
I am looking to run some data through a mapreduce and I want the output
sequence files to be compatible with Block Compressed Partitioned
LazyBinarySerDe so I can map external tables to it. The current job uses a
pojo that extends writable to serialize to disk, this is easy to read back
in for mapreduce but I am not sure how to read this with hive. Do I need to
define it as a struct, just normal fields and row format is LazyBinarySerDe?
