Dawid Wysakowicz commented on BEAM-2995:
[~huangjianhuang] I could not reproduce your exact problem, but it does not
connect to hdfs in my case if I do not add proper transformer, as explained in
BEAM-2457.

--
yes, i've read BEAM-2457 before, and tried what you suggested (with
HADOOP_CONF_DIR), but make no difference.
i started my cluster with only one host(localhost), by shell command:
FLINK_DIR/bin/start-cluster.sh
BTW, i access HDFS with HbaseIO now. it works fine on flink cluster;)

How are you starting your cluster? There was also some discussion about this on
BEAM-2457.
