Subject Re: Write Stream to HBase
Date Wed, 20 May 2015 12:26:49 GMT
Hi,
great to hear that it is working.
If the PR is going to be only about adding the "write()" method, you
probably don't need to open the PR.
https://github.com/apache/flink/pull/521 is going to add a method called:
public <OUT> DataStreamSource<OUT> createInput(InputFormat<OUT, ?>
inputFormat, TypeInformation<OUT> typeInfo)

That's exactly what you need, right?
The issue with that pull request is probably only that we have to wait for
another week until its merged.
