set SSH for root as well and give a try it will work. Steps 1) log into your host as root step 2) cd /root/.ssh Step 3) run ssh-keygen Step 4) mkdir authorized_keys Step 5) chmod 700 ~/.ssh Step 6) chmod 600 ~/.ssh/* Ex: [root@abc.ssh]# ls -lrt total 28 -rw-r--r--. 1 root root 408 Nov 26 2014 id_rsa.pub -rw-------. 1 root root 1675 Nov 26 2014 id_rsa -rw-------. 1 root root 408 Nov 26 2014 authorized_keys [root@abc .ssh]# Step 7) cat id_rsa.pub >> authorized_keys Step 😎 Validate your SSH ssh <hostname>

@Sridhar Babu M It seems you have an issue with ssh based on error message "Permission denied (publickey,password)." and I hope you are providing public key instead of private key. How many nodes do you have? Are you able to do SSH on Command Line? if yes, delete your SSH file from Ambari and add id_rsa private key.

step 1) Run below command to untar: go to files location and run below command : tar zxvf ambari-2.1.2.1-centos6.tar.gz -C /var/www/html/ tar zxvf HDP-2.3.2.0-centos6-rpm.tar.gz -C /var/www/html/ Follow link to set up local Repo link All the best.:)

@Robin Dong Here is some additional info Ambari repo link: ------------------ wget http://public-repo-1.hortonworks.com/ambari/centos6/2.x/updates/2.1.2.1/ambari-2.1.2.1-centos6.tar.gz HDP2.3.2.0 repo link: wget http://public-repo-1.hortonworks.com/HDP/centos6/2.x/updates/2.3.2.0/HDP-2.3.2.0-centos6-rpm.tar.gz as you know that if you don't have internet and trying to install on Multiple nodes first you need to setup local repository/copy files in all the nodes.. ensure that latest files/repos are showing across the cluster. Note: If you install ambari2.1.2.1 we have to go with HDP2.3.2.0 . if you are looking for HDP2.3.4 you have to install Ambari2.2.0 or later. We cann't install HDP2.3.4 with Ambari2.1.2.1

@Neeraj Sabharwal I tried your suggestion login into hivecli but didn't work and fixed the issue after followed suggestion in Ambari defect at above link workaround: ---------------------------- Under Cluster Configuration, I used Custom and entered the needed parameters instead of using Local Ambari Managed Cluster and the RA040 error is gone now. -------------------------

@Neeraj Sabharwal my cluster is not secure but we have NN HA I think this issue is hitting Ambari defect link

I enabled hive views with HDP2.3.4 and Ambari2.2.0 but getting below error. Can you provide me some hints why we are getting this error? org.apache.ambari.view.utils.ambari.AmbariApiException: RA040 I/O error while requesting Ambari org.apache.ambari.view.utils.ambari.AmbariApiException: RA040 I/O error while requesting Ambari at org.apache.ambari.view.utils.ambari.AmbariApi.requestClusterAPI(AmbariApi.java:176) at org.apache.ambari.view.utils.ambari.AmbariApi.requestClusterAPI(AmbariApi.java:142) at org.apache.ambari.view.utils.ambari.AmbariApi.getHostsWithComponent(AmbariApi.java:99) at org.apache.ambari.view.hive.client.ConnectionFactory.getHiveHost(ConnectionFactory.java:79) at org.apache.ambari.view.hive.client.ConnectionFactory.create(ConnectionFactory.java:68) at org.apache.ambari.view.hive.client.UserLocalConnection.initialValue(UserLocalConnection.java:42) at org.apache.ambari.view.hive.client.UserLocalConnection.initialValue(UserLocalConnection.java:26) at org.apache.ambari.view.utils.UserLocal.get(UserLocal.java:66) at org.apache.ambari.view.hive.resources.browser.HiveBrowserService.databases(HiveBrowserService.java:87) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at com.sun.jersey.spi.container.JavaMethodInvokerFactory$1.invoke(JavaMethodInvokerFactory.java:60) at com.sun.jersey.server.impl.model.method.dispatch.AbstractResourceMethodDispatchProvider$ResponseOutInvoker._dispatch(AbstractResourceMethodDispatchProvider.java:205)

I would suggest to use below link for RStudio issues.. https://support.rstudio.com/hc/en-us/community/posts

I hope this will help you: Ex: B1,B2,B3 business units and SA( Service Account who is loading the data into HDFS) drwxr-x--- - SA bigdata 0 2015-12-28 16:37 /db/ drwxr-x--- - SA B1 0 2015-12-28 16:37 /db/B1 Application Name/ drwxr-x--- - SA B2 0 2015-12-28 16:37 /db/B2 Application Name/ drwxr-x--- - SA B3 0 2015-12-28 16:37 /db/B3 Application Name/ bigdata(common group for all & primary group for SA) Here using simple linux permission and groups to achieve your scenarios. B1,B2 & B3 needs to add under bigdata group as well to get an access for /db dir
