schema doubt

[Rita <rm...@gmail.com>]

I have many small files (close to 1 million) and I was thinking of creating
a key value pair for them. The file name can be the key and the content can
be value.

Would it be better if I do a base64 on the content and load it to hbase or
try to echo the content for hbase shell?

Has anyone done something similar to this?

Each file is about 12k to 6k.

Inserting wont be an issue just the access. I would like to access them
quickly.

Not sure what the proper key should be. The file name is ok, but just
wondering if there is anything more I can be doing to leverage hbase.

Also could you tell how small these files are ? If they are way less than
64MB default HDFS block size you'd want to splice them before running a
MapReduce.

It sounds lik you're planning to use the HBase shell to insert all of
this data. If that's correct, I'd recommend against it. I would write
a simple MapReduce program to insert the data instead. You could run a
map-only job that reads in the files and writes each one as a row in
HBase. WIth the java APIs you can write the raw bytes pretty easily.
