I have an idea how we can reduce the impact this class of problem.
If we can detect that we are running in a distributed environment then in
order to use HBase you MUST have an hbase-site.xml
I'll see if I can make a proof of concept.

Hi Niels,
good to see that you solved your problem.
I’m not entirely sure how Pig does it, but I assume that there must be some
kind of HBase support where the HBase specific files are explicitly send to
the cluster or that it copies the environment variables. For Flink

I changed my cluster config (on all nodes) to include the HBase config dir
in the classpath.
Now everything works as expected.
This may very well be a misconfiguration of my cluster.
How ever ...
My current assesment:
Tools like Pig use the HBase config which has been specified on the LOCAL
machin
Minor correction: The HBase jar files are on the classpath, just in a
different order.

I did some more digging.
I added extra code to print both the environment variables and the
classpath that is used by the HBaseConfiguration to load the resource files.
I call this both locally and during startup of the job (i.e. these logs
arrive in the jobmanager.log on the cluster)

Till do you have some idea what is going on? I do not see any meaningful
difference between Niels code and HBaseWriteStreamExample.java. There is also a
very similar issue on mailing list as well: “Flink can't read hdfs namenode

HI,
Yes, on all nodes the the same /etc/hbase/conf/hbase-site.xml that contains
the correct settings for hbase to find zookeeper.
That is why adding that files as an additional resource to the
configuration works.
I have created a very simple project that reproduces the problem on my
setup:
https:
Is this /etc/hbase/conf/hbase-site.xml file is present on all of the machines?
If yes, could you share your code?

I look at the logfiles from the Hadoop Yarn webinterface. I.e. actually
looking in the jobmanager.log of the container running the Flink task.
That is where I was able to find these messages .
I do the
hbaseConfig.addResource(new Path("file:/etc/hbase/conf/hbase-site.xml"));

Hi,
What do you mean by saying:
> When I open the logfiles on the Hadoop cluster I see this:
The error doesn’t come from Flink? Where do you execute
hbaseConfig.addResource(new Path("file:/etc/hbase/conf/hbase-site.xml"));
?
To me it seems like it is a problem with misconfigured HBase and n
