>> 1. How to access(set/get) data stored in IGFS or IGFS as Hadoop cache?
This depeds on how do you want to access it. If you are accessing data form Hadoop, then it is not different from any other Hadoop file systems: you can use FileSystem API, "dfs" command line tool, etc.. If you want to access data through Ignite API, use IgniteFileSystem API: https://apacheignite.readme.io/docs/igfs >> 2. In IGFS as Hadoop cache mode, is core-site.xml need to be configured? (hadoop v2) Yes, it needs to be configured. >> - what shall fs.defaultFS be? "fs.defaultFS" parameter should be set to the same value as "fs.default.name" in v1. It should be URI to running IGFS instance. Please see "Configure Hadoop" and "File System URI" paragraphs here https://apacheignite.readme.io/docs/file-system for examples. Let us know if you still have outstanding questions. >> - where shall this core-site.xml file put, in hadoop path or ignite path or both? core-site.xml is only needed by Hadoop. Please put it into Hadoop path as usual. On Sun, Sep 6, 2015 at 7:14 AM, yaoqin <[email protected]> wrote: > 1. How to access(set/get) data stored in IGFS or IGFS as Hadoop cache? > > 2.
