Hi Vladimir, My bad about that ifgs://, fixed it but it changed nothing.
I don’t think Drill cares much about Hadoop settings. It never asked me to point it to an installation or configuration of Hadoop. I believe they have their own storage plugin mechanism and one of their built-in plugins happens to be the HDFS one. Here is (part of) the Drill log 2016-02-05 13:14:03,507 [294b5fe3-8f63-2134-67e0-42f7111ead44:foreman] ERROR o.a.d.exec.util.ImpersonationUtil - Failed to create DrillFileSystem for proxy user: No FileSystem for scheme: igfs java.io.IOException: No FileSystem for scheme: igfs at org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2644) ~[hadoop-common-2.7.1.jar:na] at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2651) ~[hadoop-common-2.7.1.jar:na] at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:92) ~[hadoop-common-2.7.1.jar:na] at org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2687) ~[hadoop-common-2.7.1.jar:na] at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:2669) ~[hadoop-common-2.7.1.jar:na] at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:371) ~[hadoop-common-2.7.1.jar:na] at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:170) ~[hadoop-common-2.7.1.jar:na] at org.apache.drill.exec.store.dfs.DrillFileSystem.<init>(DrillFileSystem.java:92) ~[drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.util.ImpersonationUtil$2.run(ImpersonationUtil.java:213) ~[drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.util.ImpersonationUtil$2.run(ImpersonationUtil.java:210) ~[drill-java-exec-1.4.0.jar:1.4.0] at java.security.AccessController.doPrivileged(Native Method) ~[na:1.8.0_40-ea] at javax.security.auth.Subject.doAs(Subject.java:422) ~[na:1.8.0_40-ea] at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1657) ~[hadoop-common-2.7.1.jar:na] at org.apache.drill.exec.util.ImpersonationUtil.createFileSystem(ImpersonationUtil.java:210) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.util.ImpersonationUtil.createFileSystem(ImpersonationUtil.java:202) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.store.dfs.WorkspaceSchemaFactory.accessible(WorkspaceSchemaFactory.java:150) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.store.dfs.FileSystemSchemaFactory$FileSystemSchema.<init>(FileSystemSchemaFactory.java:78) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.store.dfs.FileSystemSchemaFactory.registerSchemas(FileSystemSchemaFactory.java:65) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.store.dfs.FileSystemPlugin.registerSchemas(FileSystemPlugin.java:131) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.store.StoragePluginRegistry$DrillSchemaFactory.registerSchemas(StoragePluginRegistry.java:403) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.ops.QueryContext.getRootSchema(QueryContext.java:166) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.ops.QueryContext.getRootSchema(QueryContext.java:155) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.ops.QueryContext.getRootSchema(QueryContext.java:143) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.ops.QueryContext.getNewDefaultSchema(QueryContext.java:129) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.planner.sql.DrillSqlWorker.<init>(DrillSqlWorker.java:93) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.work.foreman.Foreman.runSQL(Foreman.java:907) [drill-java-exec-1.4.0.jar:1.4.0] at org.apache.drill.exec.work.foreman.Foreman.run(Foreman.java:244) [drill-java-exec-1.4.0.jar:1.4.0] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [na:1.8.0_40-ea] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [na:1.8.0_40-ea] at java.lang.Thread.run(Thread.java:745) [na:1.8.0_40-ea] 2016-02-05 13:14:03,556 [294b5fe3-8f63-2134-67e0-42f7111ead44:foreman] ERROR o.a.drill.exec.work.foreman.Foreman - SYSTEM ERROR: IOException: No FileSystem for scheme: igfs [Error Id: 6c95179a-6d26-498c-905f-dc18509c1651 on 192.168.1.42:31010] org.apache.drill.common.exceptions.UserException: SYSTEM ERROR: IOException: No FileSystem for scheme: igfs I copied the same ignite jars that go into Hadoop to Drill just in case but that did not help either. I think the only way is to write a Drill storage plugin for Ignite. Or somehow make the Ignite caching happen inside Hadoop and be totally transparent to Drill. Thank you for detailed help, any further ideas are as always welcome ;) Best regards, Petar -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Apache-Drill-querying-IGFS-accelerated-H-DFS-tp2840p2859.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
