Hi,

 

I'm having trouble reading files from the MapR-FS, when issueing the following command

  • hadoop fs -ls hdfs://192.168.33.10:5660/user/rsiebeling
  • or hadoop fs -ls maprfs://192.168.33.10:5660/user/rsiebeling

ls: Could not create FileClient

 

When using the command without the port everything works fine and I get the following output


Found 2 items

drwxr-xr-x   - vagrant vagrant          1 2016-05-24 00:53 hdfs://192.168.33.10/user/rsiebeling/1

The port is accessible, when I run the command telnet 192.168.33.10 5660
I get the following output

 

Trying 192.168.33.10...

Connected to 192.168.33.10.

Escape character is '^]'.

 

The CLDB master is running fine (I think), when I run the command maprcli node cldbmaster
I get the following output

 

cldbmaster

ServerID: 1898291063805227868 HostName: xxx

 

Zookeeper is also running fine, running the command maprcli node listzookeepers gives the following output

 

Zookeepers

xxx:5181

 

The setup is a one-node cluster...

 

Could you please help?

Thanks in advance,

Richard
