flink can't read hdfs namenode logical url

hi,

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

Re: flink can't read hdfs namenode logical url

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,

Thanks for your replay! I have been block in this for several days.

And I have double checked that there are hdfs-site.xml,core-site.xml,yarn-site.xml in YARN_CONF_DIR. But it is still can't read hdfs namenode logical url.

Re: flink can't read hdfs namenode logical url

Hi,

Why in this new message there is a different host? Previously code was trying to connect to “master:8020” and now it is “startdt”? If you were able to change this host somehow between runs, I guess you should be also able to set it to correct one.
