Hi Shashank,
it seems that HDFS is still not in classpath. Could you quickly explain
how I can reproduce the error?
Regards,
Timo

yes, it's working fine. now not getting compile time error.
But when i trying to run this on cluster or yarn, getting following
runtime error :
org.apache.flink.core.fs.UnsupportedFileSystemSchemeException: Could not find a
file system implementation for scheme 'hdfs'. The scheme is not directly
supported by Flink and no Hadoop file system to support this scheme could be
loaded.

while submitting job it's printing following logs so i think it's including
hdoop libs :

I would recommend to add "flink-shaded-hadoop2". That is a
bundle of all Hadoop dependencies used by Flink.

I had to include two dependencies.
hadoop-hdfs (this for HDFS configuration)
hadoop-common (this for Path)

Can you specifically guide which dependencies should
I add to extend this :

<https://github.com/apache/flink/blob/release-1.4.0-rc3/flink-connectors/flink-connector-filesystem/src/main/java/org/apache/flink/streaming/connectors/fs/Bucketer.java>
is the Hadoop-core is sufficient.

Hi,
Is this a compilation error or at runtime.
But in general, yes you have to include the
Hadoop dependencies if they're not there.
Best,

Hello,
I am trying to test 1.4.0-RC3, Hadoop
libraries removed in this version.
Actually, i have created custom
Bucketer for the bucketing sink. I am
extending
org.apache.flink.streaming.connectors.fs.bucketing.Bucketer
in the class, i have to
use org.apache.hadoop.fs.Path but as hadoop
libraries removed it's giving error
"object hadoop is not a member of package
org.apache"
Should i have to include Hadoop client libs
in build.sbt dependencies.
Thanks
Shashank
