Thomas Jungblut commented on HAMA-367:
--------------------------------------

Thanks for your contribution Apurv, you saved us a lot of time and nerves.

Just committed it. 

bq. would return a null and no compressor would be created.

In any way (but the case where the default compressor is not found in 
classpath) it returns the default compressor. In our case this is snappy.
It has a good tradeoff between amount of compression and time to compress. So 
there should be no problem.

Great we can now close this! -> Fixed!
