i am trying to setup a multi node hadoop 2.x cluster in Virtual machine,after the setup and configurations,while i try to start the cluster,node manager is not getting started in slave nodes,all other daemons are get started in the cluster,can anyone help me to resolve this issue.

I see that in your configuration:
<property>
<name>yarn.resourcemanager.hostname</name>
<value>master</value>
</property>
Node Manager is a component of YARN, on startup, this component registers with the RM. If "master" is not resolved to a valid ip address the Node Manager can't contact the resource manager.
Status is not pulled by the Resource Manager, instead is pushed by the datanodes to RM.
I think you should investigate this.

I have a 3 node cluster (1 Resource Manager, 2 Node Managers 32GB each).
I just follow the instructions from the apache flink doc YARN Setup when I started the YARN session, Flink run reports not enough resource to start AM. Then I stoped the YARN session, Flink run worked.
Application is Activated, waiting for resources to be assigned for AM. Last Node which was processed for the application : flink02.myminda.com:39826 ( Partition : [], Total resource : , Available resource : ). Details : AM Partition = ; Partition Resource = ; Queue's Absolute capacity = 100.0 % ; Queue's Absolute used capacity = 18.333334 % ; Queue's Absolute max capacity = 100.0 % ;

I'm trying to integrate hive and hbase, but when i create (external) table in hive with hbase handler:
create external table entity_hbase(id bigint, value string, ts bigint, entity_type tinyint)
stored by 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
with serdeproperties ('hbase.columns.mapping'=':key,f1:value,f1:timestamp,f1:entity_type')
tblproperties('hbase.table.name'='entity');
i get this error:
org.apache.hadoop.hbase.regionserver.NoSuchColumnFamilyException:
Column family table does not exist in region hbase:meta
First of all, i don't understand why error says that column family table (not f1) does not exist. Even if i create table in hbase and then try to create external table in hive i will get the same error.
Before all of this, my steps were:
1. start dfs
2. start yarn
3. start metastore db for hive
4. start metastore service
5. start hbase
6. using hive shell try to create table with hbase handler

We have an application managed by yarn when we change yarn-site.xml those changes are not reflected , application is still running with old configuration. We are new to Yarn any help in this regard will be helpful
Note : we have already tried restarted yarn using stop-yarn.sh and start-yarn.sh also restared dfs using start-dfs.sh and stop-dfs.sh . We are using hadoop 2.7.3
this is what yarn looks with only max memory configured to 16GB as shown in the picture but actual configuration is 22GB as per yarn-site.xml
this is the yarn-site.xml

I recently upgraded our cluster's HiveServer to HiveServer2. I also set up the Hive Metastore (in remote mode) and moved away from embedded mode (which we were previously running).
I want to test that things are properly configured and that the metatdata is acutally being stored in the remote metastore. What would be the easiest way to do this? Are their certain logs I could check to verify this behavior?
I am afraid things are not configured correctly, and I am still running my metastore in local mode, as when I query the postgresql database on the machine hosting the metastore, there are no rows in the metastore DB (despite the fact that I have created test tables through beeline).
It might be worth mentioning is that the end goal of this is to be able to query data stored in HDFS via SparkSQL. Do I need HiveServer2 to accomplish this? Apologies, I am new to a lot of this technology.
Here is my hive-site.xml:

I am planning to apply Knox to our HDP 2.2 cluster but I encountered the hiveserver2 http mode connection. I configured hive-site.xml like below:
<property>
<name>hive.server2.enable.doAs</name>
<value>true</value>
</property>
<property>
<name>fs.hdfs.impl.disable.cache</name>
<value>true</value>
</property>
<property>

<value>true</value>

</property>
<property>
<name>hive.server2.thrift.http.path</name>
<value>cliservice</value>

<value>5</value>
</property>
<property>
<name>hive.server2.thrift.http.max.worker.threads</name>
<value>100</value>
</property>
However, when I try to connect to the server via beeline, the beeline hangs. There is no exception and error messages in the log file. If I change the transport mode to "biniary", the problem is totally gone. I don't know why it happens.
What should I do for that?
