hdfs - ls: Failed on local exception: com.google.protobuf.InvalidProtocolBufferException:

cloudera, hadoop, hdfs

Solution

HDFS is not running at 50075. To check your hdfs port use the following command in linux

hdfs getconf -confKey fs.default.name

You will get the output something like

hdfs://hmaster:54310

And correct your URL accordingly

Problem

I am trying to use the below to list my dirs in hdfs: ``` ubuntu@ubuntu:~$ hadoop fs -ls hdfs://127.0.0.1:50075/ ls: Failed on local exception: com.google.protobuf.InvalidProtocolBufferException: Protocol message end-group tag did not match expected tag.; Host Details : local host is: "ubuntu/127.0.0.1"; destination host is: "ubuntu":50075; ``` Here is my /etc/hosts file ``` 127.0.0.1 ubuntu localhost #127.0.1.1 ubuntu # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ``` How do I properly use hdfs:// to list my dirs? I am using couldera 4.3 on ubuntu 12.04
