Reading from HBase problem

[Hilmi Yildirim]

Hi,
I implemented a simple Flink Batch job which reads from an HBase Cluster
of 13 machines and with nearly 100 million rows. The hbase version is
1.0.0-cdh5.4.1. So, I imported hbase-client 1.0.0-cdh5.4.1.
I implemented a flatmap which creates a tuple ("a", 1L) for each row .
Then, I use groupBy(0).sum(1).writeAsTest. The result should be the
number of rows. But, the result is not correct. I run the job multiple
times and the result flactuates by +-5. I also run the job for a smaller
table with 100.000 rows and the result is correct.

Does anyone know the reason for that?

Best Regards,
Hilmi
