Subject Re: flink can't read hdfs namenode logical url
Date Fri, 20 Oct 2017 13:39:46 GMT
Hi,

Please double check the content of config files in YARN_CONF_DIR and HADOOP_CONF_DIR (the
first one has a priority over the latter one) and that they are pointing to correct files.

Also check logs (WARN and INFO) for any relevant entries.
