Subject: StandAlone job on k8s fails with "Unknown method truncate" on restore

The job uses a RolllingFileSink to push data to hdfs. Run an HA standalone
cluster on k8s,

* get the job running
* kill the pod.

The k8s deployment relaunches the pod but fails with Missing data in tmp file:
Unknown method truncate called on
org.apache.hadoop.hdfs.protocol.ClientProtocol protocol.
The file does exist. We work with hadoop 2.6 , which does no have truncate.
The previous version would see that "truncate" was not supported and drop a
length file for the ,inprogress file and rename it to a valid part file.

Is this a known issue ?
