If I want to write the Reducer output into HBase, I just need to use:
context.write(key,put);
My question is about the first parameter “key”; whatever value I set to “key”, it will not be showed in HBase when I use HBase Shell to check, even though I set it to “null”. So what should I set to this “key” on earth? You should set it to null - the put value contains both the key and value from HBase perspective and as you correctly noted the context’s key is not used.

Hi Sandeep,

Not sure which webMethods product you are using and what is the context of this query, can you please provide more details.
