Strange, I'm using Flink 0.8.1 and HBase 0.98.6 and everything works fine (at least during reading). Remember to put the correct hbase-site.xml in the classpath! To output data I'm trying to find the best way to achieve it.. It came out that the hadoop compatibility layer of flink probably doesn't

2015-03-31 Thread Kostas Tzoumas
I like the fact that the naming scheme follows some logic. I also like that we have two easy to understand concepts: - Operator (be that in any of the above representations) - Result (of executing an operator) +1 On Tue, Mar 31, 2015 at 4:50 PM, Ufuk Celebi u...@apache.org wrote: On a high

Hi! Also important: Which Hadoop version are you using with Flink? The problem is a missing method in a Hadoop class, so I guess there is a Hadoop version mismatch. For all Flink versions, there is a package for Hadoop 1.x and a package for Hadoop 2.x . Make sure you pick the right one for HBase

Hi Flink devs, this is my final report about the HBaseOutputFormat problem (with Flink 0.8.1) and I hope you could suggest me the best way to make a PR: 1) The following code produce the error reported below (this should be fixed in 0.9 right?) Job job = Job.getInstance();

Re: [DISCUSS] Inconsistent naming of intermediate results

2015-03-31 Thread Stephan Ewen
I like getting the consistency in there. I was never thinking of the intermediate data sets to be strictly produced by a vertex, so I am unsure whether we should use that exact naming scheme, or one that disconnects the results from the term VertexResult. On Tue, Mar 31, 2015 at 5:27 PM, Kostas
