Leo commented on HDFS-5088:
---------------------------
Now, the problem is that it always uses the default fs even I specify hdfs
paths as follows
java org.apache.hadoop.hdfs.tools.HDFSConcat hdfs:///a hdfs:///b
> Exception in thread "main" java.lang.ClassCastException:occurs when running
> java org.apache.hadoop.hdfs.tools.HDFSConcat

> Key: HDFS-5088
> URL: https://issues.apache.org/jira/browse/HDFS-5088
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs-client
> Environment: Fedora 19, 16 bit
> Reporter: Leo
>
> When I run this command,
> java org.apache.hadoop.hdfs.tools.HDFSConcat
> I get the following exception
> Exception in thread "main" java.lang.ClassCastException:
> org.apache.hadoop.fs.LocalFileSystem cannot be cast to
> org.apache.hadoop.hdfs.DistributedFileSystem
> at org.apache.hadoop.hdfs.tools.HDFSConcat.main(HDFSConcat.java:46)
> It's because that the default fs is localfs instead of hdfs.
