Hadoop Multi-tenant cluster setUp

+3 votes
554 views

  1. How Hadoop provides Multi-tenancy using scheduler's or in simple terms "WHAT ARE THE STEPS TO CONFIGURE A MULTI-TENANT HADOOP CLUSTER?"
    Here multi-tenancy means different users can run there applications(similar/different) in a way such that each user is completely unaware of other and one user can't interfere with other user's data in hdfs such that data is secure and each user gets its fair proportion of resources to execute its applications in parallel.

  2. And is there any way to verify that cluster tenants are able to get their applications executed easily without any other intervention while keeping their data not secure and safe in hdfs?

Hadoop client setup to access remote cluster

I have setup a HDP 2.3 cluster on Linux(CentOS). Now I am trying to utilize my ETL programs to access this cluster from a windows environment.
Should I setup Apache Hadoop on Windows local/server. What setup should I do ? What goes into the core-site.xml (mention my remote HDFS url ?/)
Any pointers would be helpful.

Windows and Linux hadoop cluster

Please let me know if it's feasible to have hadoop cluster with data nodes running on multiple Operating systems. For instance few data nodes running on windows server and others on linux based OS (RHEL,centOS).

If above scenario is feasible then please provide configuration settings required in various xml files(hdfs-site.xml,core-site.xml,mapred-site.xml,yarn-site.xml) and environment files(hadoop-env.sh/hadoop-cmd.sh) for windows and linux data nodes and namenode.

Uneven load balance between hadoop cluster

I am experiencing a very uneven load balance between the different machines that compose my little cluster.

I have a cluster of four machine and only one is actually used...

This happen when I run terasort, however, if I run teragen, everything works just fine, with the load evenly distributed.

Do you have any hints? In what direction I should look ?

How do I customize data placement on DataNodes (DN) of Hadoop cluster?

Let we change the default block size to 32 MB and replication factor to 1. Let Hadoop cluster consists of 4 DNs. Let input data size is 192 MB. Now I want to place data on DNs as following. DN1 and DN2 contain 2 blocks (32+32 = 64 MB) each and DN3 and DN4 contain 1 block (32 MB) each. Can it be possible? How to accomplish it?

Two hadoop nodes on same machine while a second machine not joining the cluster

I have a test cluster of two machines, on both of them hadoop is installed. I have configured the hadoop cluster but on admin UI (as in the below picture) I see that two nodes are running on the same master machine, and that the other machine has no Hadoop node.

On master machine following services are running:

~$ jps 26310 ResourceManager 27593 Jps 26216 DataNode 26135 NameNode 26557 NodeManager 26701 JobHistoryServer

On the slave machine:

~$ jps 2614 DataNode 2920 Jps 2707 NodeManager

I don't why the slave is not joining the cluster (It was before). I tried to shutdown all servers on both machines and format HDFS then restarting everything but that didnot help. Any help to figure whats causing that behavior is appreciated.
