> Key: FLINK-1828
> URL: https://issues.apache.org/jira/browse/FLINK-1828
> Project: Flink
> Issue Type: Bug
> Components: Hadoop Compatibility
> Affects Versions: 0.9
> Reporter: Flavio Pompermaier
> Labels: hadoop, hbase
> Fix For: 0.9
>
>
> Right now it is not possible to use HBase TableOutputFormat as output format
> because Configurable.setConf is not called in the configure() method of the
> HadoopOutputFormatBase
