Hbase Connector failed when deployed to yarn

hai

Hello:

    I am new to flink, and I copy the official Hbase connector examples from source 

flink/flink-connectors/flink-hbase/src/test/java/org/apache/flink/addons/hbase/example/HBaseWriteExample.java

and run in a yarn-cluster with the command: 

bin/flink run -m yarn-cluster -yn 2 -c {class-path-prefix}.HBaseWriteExample {my-application}.jar

What I have get is:

------------------------------------------------------------
 The program finished with the following exception:

Re: Hbase Connector failed when deployed to yarn

Hi

I believe this is the same problem which reported in https://issues.apache.org/jira/browse/FLINK-12163 , current work around solution is to put flink-hadoop-compatibility jar under FLINK_HOME/lib.

Hi, Tang:


Thaks for your reply, will this issue fix soon？I don’t think put flink-hadoop-compatibility jar under FLINK_HOME/lib is a elegant solution.

Hi,

The Jira issue is still unassigned.
Would you be up to work on a fix?

Best, Fabian

Thaks for your reply, will this issue fix soon？I don’t think put flink-hadoop-compatibility jar under FLINK_HOME/lib is a elegant solution.

Hi

I believe this is the same problem which reported in https://issues.apache.org/jira/browse/FLINK-12163 , current work around solution is to put flink-hadoop-compatibility jar under FLINK_HOME/lib.
