Thanks for your help. But unfortunatly this didn’t do the job. Here’s
the Shellscript I’ve written to start my cluster (the scripts on the
other node only contains the command to start the datanode
respectively the command to start the Nodemanager on the other node
(with the right user (hdfs / yarn)):
#!/bin/bash
# Start
HDFS-------------------------------------------------------------------------------------------------------------------------
# Start Namenode
su - hdfs -c "$HADOOP_PREFIX/sbin/hadoop-daemon.sh --config
$HADOOP_CONF_DIR --script hdfs start namenode"
wait
# Start all Datanodes
export HADOOP_SECURE_DN_USER=hdfs
su - hdfs -c "$HADOOP_PREFIX/sbin/hadoop-daemon.sh --config
$HADOOP_CONF_DIR --script hdfs start datanode"
wait
ssh root@hadoop-data.klinger.local 'bash startDatanode.sh'
wait
# Start Resourcemanager
su - yarn -c "$HADOOP_YARN_HOME/sbin/yarn-daemon.sh --config
$HADOOP_CONF_DIR start resourcemanager"
wait
# Start Nodemanager on all Nodes
su - yarn -c "$HADOOP_YARN_HOME/sbin/yarn-daemon.sh --config
$HADOOP_CONF_DIR start nodemanager"
wait
ssh root@hadoop-data.klinger.local 'bash startNodemanager.sh'
wait
# Start Proxyserver
#su - yarn -c "$HADOOP_YARN_HOME/bin/yarn start proxyserver --config
$HADOOP_CONF_DIR"
#wait
# Start Historyserver
su - mapred -c "$HADOOP_PREFIX/sbin/mr-jobhistory-daemon.sh start
historyserver --config $HADOOP_CONF_DIR"
wait
This script generates the following output:
starting namenode, logging to
/var/log/cluster/hadoop/hadoop-hdfs-namenode-hadoop.klinger.local.out
starting datanode, logging to
/var/log/cluster/hadoop/hadoop-hdfs-datanode-hadoop.klinger.local.out

Following my stopscript and it’s output:
#!/bin/bash

nodemanager did not stop gracefully after 5 seconds: killing with kill -9

Is there may be anything wrong with my commands?

*Betreff:* Re: Hadoop 2.6.0 - No DataNode to stop
1.Stop the service
2.Change the permissions for log and pid directory once again to hdfs.
3.Start service with hdfs.
This will resolve the issue

Hi
Did you check your slaves file is correct ?
That the datanode process is actually running ?
Did you check its log file ?
That the datanode is available ? (dfsadmin -report, through the WUI)
We need more detail

Hello,
I used a lot of Hadoop-Distributions. Now I’m trying to
install a pure Hadoop on a little „cluster“ for testing (2
CentOS-VMs: 1 Name+DataNode 1 DataNode). I followed the
instructions on the Documentation site:
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/ClusterSetup.html.
I’m starting the Cluster like it is described in the
Chapter „Operating the Hadoop Cluster“(with different
users). The starting process works great. The PID-Files
are created in /var/run and u can see that Folders and
Files are created in the Data- and NameNode folders. I’m
getting no errors in the log-files.
When I try to stop the cluster all Services are stopped
(NameNode, ResourceManager etc.). But when I stop the
DataNodes I’m getting the message: „No DataNode to stop“.
The PID-File and the in_use.lock-File are still there and
if I try to start the DataNode again I’m getting the error
that the Process is already running. When I stop the
DataNode as hdfs instead of root the PID and in_use-File
are removed but I’m still getting the message: „No
DataNode to stop“
What I’m doing wrong?
