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.

hi,

I start yarn-ssession.sh on yarn, but it can't read hdfs logical url. It always connect to <a href="hdfs://master:8020" class="">hdfs://master:8020, it should be 9000, my hdfs defaultfs is <a href="hdfs://master" class="">hdfs://master.

I have config the YARN_CONF_DIR and HADOOP_CONF_DIR, it didn't work.

Is it a bug? i use flink-1.3.0-bin-hadoop27-scala_2.10
