Hi there, I configured hadoop-cephfs plugin and try to use cephfs as a replacement. I had sucessfully configured
hadoop-env.sh with setting the HADOOP_CLASSPATH for hadoop-cephfs.jar But when I run hadoop fs -ls /, I got the following exception. Looks like it cannot find the actual jar for both hadoop-cephfs.jar and libcephfs-java.jar I placed these two in the /usr/local/hadoop/lib directory and edited the hadoop classpath in hadoop-env.sh How could this issue be ? Thanks anyone for kind response. java.lang.RuntimeException: java.lang.ClassNotFoundException: Class org.apache.hadoop.fs.ceph.CephFileSystem not found at org.apache.hadoop.conf.Configuration.getClass(Configuration.java:2195) at org.apache.hadoop.fs.FileSystem.getFileSystemClass(FileSystem.java:2638) at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2651) at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:92) at org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2687) at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:2669) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:371) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:170) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:355) at org.apache.hadoop.fs.Path.getFileSystem(Path.java:295) at org.apache.hadoop.fs.shell.PathData.expandAsGlob(PathData.java:325) at org.apache.hadoop.fs.shell.Command.expandArgument(Command.java:235) at org.apache.hadoop.fs.shell.Command.expandArguments(Command.java:218) at org.apache.hadoop.fs.shell.Command.processRawArguments(Command.java:201) at org.apache.hadoop.fs.shell.Command.run(Command.java:165) at org.apache.hadoop.fs.FsShell.run(FsShell.java:287) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84) at org.apache.hadoop.fs.FsShell.main(FsShell.java:340) Caused by: java.lang.ClassNotFoundException: Class org.apache.hadoop.fs.ceph.CephFileSystem not found at org.apache.hadoop.conf.Configuration.getClassByName(Configuration.java:2101) at org.apache.hadoop.conf.Configuration.getClass(Configuration.java:2193) ... 18 more
