[debanjandhar]

I am trying to run sequenceiq/hadoop-docker:2.4.1 in docker as :

docker run -i -t sequenceiq/hadoop-docker:2.4.1 /etc/bootstrap.sh -bash

and getting the following error :

Any reason why am getting the same?

Currently working on CENTOS 7 with kernel version : 3.10.0-514.2.2.el7.x86_64

no mappe 9000 port

no mappe 9000 port

actually there is. in core-site.xml it is written <value>hdfs://hadoop-master:9000/</value>

but the thing is, 9000 port not exposed outside of docker. You should add -p 9000:9000 after -p 8088:8088 to start-container.sh script, when starting hadoop-master container.
