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.

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 mapreduce code,
For eg, the input file has oneĀ  attribute named currency , it will have a
master table currency. need to match both values to print it.

The table which has lookup takes long time to get load. For 13250 records
it take 59 mins.

How to make fine tune to reduce the time for its loading.

Please help.

Thanks in advance.
