robert created HDFS-13474:
-----------------------------
Summary: Unable to start Hadoop DataNodes
Key: HDFS-13474
URL: https://issues.apache.org/jira/browse/HDFS-13474
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: 3.1.0
Reporter: robert
Attachments: hadoop-roycecollige@steelydan.com-datanode-c0315.log, hadoop-roycecollige@steelydan.com-datanode-c0315.out, hadoop-roycecollige@steelydan.com-namenode-c0315.log, hadoop-roycecollige@steelydan.com-namenode-c0315.out, hadoop-roycecollige@steelydan.com-secondarynamenode-c0315.log, hadoop-roycecollige@steelydan.com-secondarynamenode-c0315.out
I am trying to follow the instrutions in the GettingStarted guide,
[http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html#YARN_on_Single_Node]
I have confirmed, that I can `ssh localhost` without a password prompt. I have also run the following steps,
{quote}1. $ bin/hdfs namenode -format
2. $ sbin/start-dfs.sh
{quote}
But I cant run step 3. to browse the location at `[http://localhost:9870/]`. When I run `>jsp` from the terminal prompt I just get returned,
{quote}14900 Jps
{quote}
I was expecting a list of my nodes.
In the Logs I see two error messages towards the end,
{quote}2018-04-18 14:15:42,516 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: RECEIVED SIGNAL 15: SIGTERM
{quote}
{quote}2018-04-18 14:15:42,516 ERROR org.apache.hadoop.hdfs.server.datanode.DataNode: RECEIVED SIGNAL 1: SIGHUP

I will attach the full logs with this bug report.
Can anyone help even with ways to debug this please ?
