In your mapreduce, in the mapper.setup() read the lookup tables in to memory
and then access them as needed in your Mapper.map() method.
Same for reducer...
See mapper joins in Map/Reduce ...

Hi Ranjini,
can you tell more about the lookup?
A lookup to another HBase table?
For 13k records you would not need the complexity of HBase.

Hi,
I have a input File of 16 fields in it.
Using Mapreduce code need to load the hbase tables.
The first eight has to go into one table in hbase and last eight has to got
to another hbase table.
The data is being loaded into hbase table in 0.11 sec , but if any lookup
is being added in the map
