poseidon 使用hdfs的bug(将mock

1.dist/index-0.1/lib里的docformat,index,indexmeta的jar包分别为(build.sh生成的)： index-0.1.jar，indexmeta-0.1.jar，docmeta-0.1.jar 但是start.sh却写着： cmd="$HADOOP jar ${current_dir}/lib/docmeta-1.0-SNAPSHOT.jar ... cmd="$HADOOP jar ${current_dir}/lib/index-1.0-SNAPSHOT.jar ... cmd="$HADOOP jar ${current_dir}/lib/indexmeta-1.0-SNAPSHOT.jar ...

2.start.sh在某些情况下时无法正确的将dist/index-0.1/lib中的jar包加入HADOOP_CLASSPATH,导致hadoop jar docmeta-1.0.jar...命令会报错，no class found meta/MetaConfigured。

3.hadoop jar docmeta-1.0.jar....会报如下错误： java.io.IOException: Incomplete HDFS URI, no host: hdfs:/// at org.apache.hadoop.hdfs.DistributedFileSystem.initialize(DistributedFileSystem.java:143) at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2653) 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.mapreduce.lib.input.FileInputFormat.addInputPath(FileInputFormat.java:520) at meta.MetaConfigured.run(MetaConfigured.java:97) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70) at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:84) at meta.DocMetaConfigured.main(DocMetaConfigured.java:22) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.hadoop.util.RunJar.run(RunJar.java:221) at org.apache.hadoop.util.RunJar.main(RunJar.java:136) 但etc/test.json里的namenode是配了的。所以不知道为什么会报no host。
