Re: Hadoop client configuration IGFS - hdfs dfs

Hello! Unfortunately I'm not familiar enough with IGFS to answer such question purely from configuration variables. What does it say when it does not work? Have you tried starting Ignite client in the same VM prior to the launch? If you don't have Ignite client, you will have to use IPC.

Re: Hadoop client configuration IGFS - hdfs dfs

Hello! It seems that Igfs can try use client node from the same process if fs.igfs.igfs.endpoint.no_embed is set to false. But you have it set to true. In this case it will use IPC by host/port. Regards, -- Ilya Kasnacheev чт, 23 мая 2019 г. в 17:20, joaquinsanroman : > Hi, > > Yes, this

Hi Ilya, I am not using SHMEM, because the client and the servers are in different hosts. If I use @localhost:10500, I will never connect because in localhost is not running one node of ignite. My intention is to connect to one cluster remotely. Do you know how to do it? Thank you very much,
