> We build Integration tests using this kind of code: 
> {code:java}
> val bucketingSink = new BucketingSink[Row]("hdfs:///user/$USER)}/application_name/")
> bucketingSink.setFSConfig(hadoopRule.getConfiguration.hdfs)
> bucketingSink.setBucketer(new DateTimeBucketer[Row]("yyyy-MM-dd--HHmm"))
> outpuStream.addSink(bucketingSink)
> {code}
> Here, the hadoopRule is providing a valid hdfs config that should allows this kind of code to run on a machine with no HADOOP_HOME or HADOOP_CONF_DIR set up, like a developper workstation or a Jenkins slave.
> When running this code on such a machine, the .createHadoopFileSystem(...) fails with 
> {noformat}
> The given file system URI (hdfs:///user/$USER/application_name/) did not describe the authority 
> at org.apache.flink.runtime.fs.hdfs.HadoopFsFactory.create(HadoopFsFactory.java:149)
> at org.apache.flink.core.fs.FileSystem.getUnguardedFileSystem(FileSystem.java:401){noformat}
> because it tries to instantiate the fileSystem from a default configuration in .getUnguardedFileSystem() ; as the default conf doesn't exist, the default filesystem resolves to "file:///" and the checks of the consistency of the URI fails because no authority can be found So the whole filesystem creation fails before actually trying to use the provided config.
