We are using hadoop 2.7.3 changed the hdfs-site.xml to point to new directory provided permissions on new directory too ...and ran start-dfs.sh and stop-dfs.sh ..on name node ...but changes are not taking effect it still points to the old directory ...
Am I missing anything while doing the configuration changes? And how can we make sure to use the new directory?
it's a multi node cluster
this is the hdfs-site.xml on name node

I tried running a mapreduce job in Hadoop 2.8.5 but it keeps running.

I am running Hadoop on ubuntu and my pc have intel i7 processor with 16 gb RAM and 256 GB SSD
YARN's Resource Manager need compute resources from Node Manager(s) in order to run anything. Your Node Manager shows it's local directory is bad. Which means you have no compute resources available (which is verified looking at your cluster metrics. See all the zeros.) which is why your application is stuck in "ACCEPTED".
Fix your yarn.nodemanager.local-dirs and make sure YARN has full permissions on it to proceed.
I've setup a hadoop cluster with one master node and 3 datanodes. When I try to run a mapreduce job on the master node I get the following error:
18/05/23 19:22:59 INFO mapreduce.Job: Task Id : attempt_1527096061793_0001_m_000000_0, Status : FAILED

I've managed to find the error in the data nodes log files as well but they don't say anything more than has been shown in the console. I'm really stuck for quite some time now and I'm not sure how to approach this one. Any suggestions or help is appreciated.
Thanks

Hadoop version is 2.7.6
I found the problem. It was in the mapred-site.xml configuration file on these lines here:
<property>
<name>mapreduce.map.java.opts</name>
<value>1600</value>
</property>
<property>
<name>mapreduce.reduce.java.opts</name>
<value>1600</value>
</property>
Every value inside the tag should have an "-Xmx" prefix and an "m" suffix.
The right way to configure these properties:
<property>
<name>mapreduce.map.java.opts</name>
<value>-Xmx1600m</value>
</property>
<property>
<name>mapreduce.reduce.java.opts</name>
<value>-Xmx1600m</value>
</property>
Hope this helps someone as it took way too much of my time to figure it out.
I'm new to hadoop,hive, hbase and kylin. I tried to install thoose first three, and it's seems to be working.
After that I tried to install apache kylin, run the sample.sh and success.
After running the script I restart and open the web interface. Some page cannot be opened ex: /cube, /models, /admin/config
The problem is: I can see there are 5 tables created in hive, and also 2 cubes created. But when I open in web gui, the models is in loading-state and I cannot build the cube.
When I try to build the cube
I cannot find any infomative log (Or maybe there is one, but I don't know about it)

For kylin, I use default configuration, because I don't really know what to do with the kylin configuration.
What i use:
hadoop 2.7.5 binary
hbase 1.2.6 binary
hive 1.2.2 binary
kylin 2.2.0 source (I just add logs)
I'm preparing hadoop cluster on four very small virtual servers (2GB RAM, 2Cores each) for a proof of concept.
One server as name node and resource manager and three are data nodes.
Every time I'm running the test job (3,4 GB file with data) - two of data nodes (random ones) are working at maximum capability and one of them is sleeping (monitoring via htop).
All 3 data nodes are visible in the hadoop GUI.
What am I missing?
Any help will be much appreciated.

I found the solution.
To increase number of reducers in the file mapred-site.xml I added
<property>
<name>A</name>
<value>5</value>
</property>
After I added additional nodes to cluster, hadoop has increased mappers without any additional change in the configuration. All data nodes are working at maximum capability now.
I have just configured a hadoop clustering by using cdh5.I could successful run test jobs in command line and get the results.resourcemanager ui doesnot show job status,even in the completion .If I set mapreduce.framework.name to yarn in mapred-site.xml and job fails and show failure status in the resourcemanager ui.
Test job,I have used to run
yarn jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples-2.5.0-cdh5.3.1.jar pi 16 10000
