1. Please make sure IGFS is really used: e.g. you may explicitly locate some table data on IGFS, and run the queries upon. IGFS statistics can partially be observed through Visor. Also please note, that upon node(s) start IGFS is empty. In case of dual modes it caches the data upon file reading. In case of primary mode you need to put some data onto the file system before you can use it. So, data read performance boost can be seen only when some data are already cached in IGFS, and read from there rather than from disk.
2. Can you specify data and the query , so that we could reproduce the issue? (E.g. you can use some publicly available sample data from Hive examples.) 3. No. The nodes should connect without additional effort. Can you please attach full logs of all nodes where this situation happens? -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/HDP-Hive-Ignite-tp12195p12355.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
