I'm trying to create an input file in the hdfs using this command :
hduser#salma-SATELLITE-C855-1EQ:/usr/local/hadoop$ ./bin/hadoop fs -mkdir /in
but it gives me an error that the connection failed :

I already run hadoop service with start-all.sh :
hduser#salma-SATELLITE-C855-1EQ:/usr/local/hadoop$ jps
20437 Jps
20030 SecondaryNameNode
19839 DataNode
So can anyone help to solve this problem
Your are missing the namenode ( primary ) this is where you code is attempitng to connect. Check the log to understand why it does not started.

I am using Hadoop 2.6.0 and oozie 5.2.0 version.
Trying to run example Map reduce job in oozie but getting below error.

Not sure if I have to change any configurations. I tried giving public dns in job.properties file instead of localhost but still got the same error. Any help is appreciated.
Call From ip-172-31-84-37/172.31.84.37 to localhost:8020 seems to say that your Oozie server (on localhost) is not running HDFS on port 8020. Use the wiki page in the error to debug your network setup...
Assuming you have an external HDFS address, then fs.defaultFS in $HADOOP_CONF_DIR/core-site.xml needs updated with the correct address.

I use HDP3.1. And I Ambari to deploy hadoop cluster and hive. After deployed, I can run hive in shell successfully. And then I deploy Apache Kylin2.6, it can sync hive table. But when I build the cube, I got the following error:

I run hive command in shell. It's success. The connection string is same as the string when run build cube in kylin. I'm confused why it is success in shell but failed in building cube.

You can try to add these two properties to hive-site.xml.
<property>
<name>hive.security.authorization.sqlstd.confwhitelist</name>
<value>mapred.*|hive.*|mapreduce.*|spark.*</value>
</property>
<property>
<name>hive.security.authorization.sqlstd.confwhitelist.append</name>
<value>mapred.*|hive.*|mapreduce.*|spark.*</value>
</property>
Finally, I found the root cause. There is 'Cannot modify dfs.replication at runtime.' error message in the error log. Kylin set this property in $KYLIN_HOME/conf/kylin_hive_conf.xml. And when it is running hive command, it will auto append the properties in that file. The final command likes: hive --hiveconf dfs.replication=2 ..........
It looks like that dfs.replication property can't be appened to hive command. I removed this property in kylin_hive_conf.xml. And it works now.
I am trying to run hive using a user other than the hadoop user.
When I run hive, I get the error below. I guess Hive is trying to access the root directory. How do I change the inode directory to /user/fratboy? I have already created this in hdfs and changed the owner to fratboy.

you can try the following:
if you have root permission: #sudo -u hdfs hdfs dfs -chmod 775 /
This will change the permissions on / to drwxrwxr-x, which gives permission to your user fratboy.
Make such that the /user already exist on /
hope this help
I am following this document to test the sentiment analysis - can someone please help me out -- thanks!!
