Hi mbigelow, Thanks for your reply. Appreciate it.

Hi , I got the error as below. It seems we need to set memory for physical memory , but i can't find the configation about it. Where can i set physical memory? But the way , i just run some simple insert query in HIVE, and this error not happened on every time , i want to get the reason. ERROR: Diagnostic Messages for this Task: Container [pid=51661,containerID=container_e50_1493005386967_25486_01_000243] is running beyond physical memory limits.

Sorry for late reply. I need to test it after business time. I set it to 2046->1024->512-> 256 and found NetWork IO take a low value with the number reducing. I'm sure the parameter is working for it. For someone who will refer this ticket. The speed of data transformation will take a very low speed for NetworkIO if you set a low value to this parameter. so please adjust schedul of jobs.

wenjie · ‎04-09-2017

Yes, I set it from 4096 to 2048. The Network IO at the same level when it was 4096. Maybe i need to set less number than 2048?

wenjie · ‎04-06-2017

It looks it( Maximum Number of Transfer Threads ) is not working. I set it from 4096 to 2048 , but NetworkIO still take a high value.

wenjie · ‎04-03-2017

Thanks Fawze. I will try it and take a feedback.

Hi , I want to limit speed of data transformation with CDM because other process * (Not bigdata , not CDH) is using same internet resource with it(CDM). and the process* can't be run as no resource. How can i set it in CHM? I tried to set 'DataNode Balancing Bandwidth' in HDFS configuration to 1Mb. But it looks not working.

Hi , I have a host in existing system as balancer and datanode. And because it can't be used from new week so I added a new host to instead of it. Now i can find the new host and set it as a datanode. My question is how can i change balancer from old host to new host? I confirmed the doc as below, but can't find related contents about it. https://www.cloudera.com/documentation/enterprise/5-8-x/topics/admin_hdfs_balancer.html Thanks , Wenjie Ps. I can't find related link in the page.

wenjie · ‎03-22-2017

I installed the host again , and the problem has been fixed. I'm not sure the reason.

wenjie · ‎03-20-2017

I created a new ticket for this problem as a summury, but i can't find it , why? I move it to here. I want to add a host to existing cluster as a datanode. But the host don't work fine as expected. 1, I confirmed status of agent and it is working fine. cloudera-scm-agent (pid 162575) is running... 2, I restarted the cluster and CDM , the problem can't be resolve. 3, I stopped agent and add the host and restart agent again , the problem can't be resolve also. Looking forward to your response. And please let me know if you want more info. Thanks, Wenjie

wenjie · ‎03-20-2017

NO , The problem has not be resolved.

wenjie · ‎03-20-2017

Hi , I want to add a host to existing cluster as a datanode. But the host don't work fine as expected. And i found the message in detail of host. and the log 1, I confirmed status of agent and it is working fine. cloudera-scm-agent (pid 162575) is running... 2, I restarted the cluster and CDM , the problem can't be resolve. 3, I stopped agent and add the host and restart agent again , the problem can't be resolve also. Looking forward to your response. And please let me know if you want more info. Thanks, Wenjie

wenjie · ‎03-17-2017

I restarted the CDM and HOST MONITOR, it still can't be resloved. And i can't find CDH version in host list also for new host. By the way , HOST MONITOR service and other datanode (existing) is working fine. so i guess some setting in new host is not good.

wenjie · ‎03-17-2017

I restarted the agent in host. But can't reslove it . And i found i can't get the CDH version ("None") in the host list. But existing datanode shows "CDH 5"

wenjie · ‎03-17-2017

Hi csguna , Working fine. I want to add a new datanode to existing system. and existing system is working fine . The added host not work well only.

wenjie · ‎03-17-2017

I restarted host monitor , but it still not working.

wenjie · ‎03-16-2017

And i confirmed the log of host and found it. Caught unexpected exception in main loop. Traceback (most recent call last): File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/cmf-5.10.0-py2.6.egg/cmf/agent.py", line 710, in __issue_heartbeat self._init_after_first_heartbeat_response(resp_data) File "/usr/lib64/cmf/agent/build/env/lib/python2.6/site-packages/cmf-5.10.0-py2.6.egg/cmf/agent.py", line 881, in _init_after_first_heartbeat_response assert response_data.get("cm_guid") is not None AssertionError

wenjie · ‎03-16-2017

i'm sure i started agent in the host(datanode). /etc/init.d/cloudera-scm-agent status cloudera-scm-agent (pid 112359) is running...

wenjie · ‎03-16-2017

Hi , I want to add a host to cluster as a datanode. Now i can find the host in host list and adding the New Hosts to existing Cluster. it looks it takes time because i began it 1hours ago but it is still running. And i can find it in the cluster with new windows even the processing is running. Bus Health test is bad. "This host is in contact with the Cloudera Manager Server. This host is not in contact with the Host Monitor." How can i investigate it ?

wenjie · ‎03-13-2017

Got it！ Thanks for your reply.

Hi, I want to add a data node to existing system , where can i find the manual or other? I tried to find it in this site, but i couldn't find content related it. Regards, wenjie

I investigate about it and found it is related with calltime option of HIVE. My question is , Where can i find this option in cloudera manager ? HiveOptions.callTimeout?

wenjie · ‎02-26-2017

@saranvisa Yes , you are right . I can't connect the host and i will apply it. Thanks a lot.

wenjie · ‎02-26-2017

When i tried to open WEBUI of IMPARA in cloudera Manager , it's not working. It looks the page can't be found as i got a blank page with error message . and i executed reflesh command with command mode in Linux also , it's working fine. Could you please give me some idea about it?
