Hi，

   I have a issue in CDH cluster。The cluster has been running a few days。But Today， in CM Host Tab，The Host Machine Health Test show ：

This host is in contact with the Cloudera Manager Server. This host is not in contact with the Host Monitor.

The Health History show Error then becomes healthy。

CM Agent log：

I didn't find the re-editing option, and all the images showed an error. So I describe my problem again.

 

Hi，

   I have an issue in CDH cluster. The cluster has been running for a few days.But Today, in CM Host Tab,The Host Machine Health Test shows :

  This host is in contact with the Cloudera Manager Server. This host is not in contact with the Host Monitor.

 

The Health History show Error then becomes healthy.

@zy001,

 

Thanks for discussing the issue you are facing.

This issue does not pose any threat to the functionality of your cluster, so the impact should be minimal.

 

Let's start with what we know:

 

- agent attempts to make an HTTP connection and gets the following:

 

[29/Dec/2018 16:45:08 +0000] 24147 MonitorDaemon-Reporter throttling_logger ERROR (3 skipped) Error sending messages to firehose: mgmt-SERVICEMONITOR-02008505edb7b85b2295119db7eba412

. . . .

File "/usr/lib64/python2.7/socket.py", line 224, in meth
return getattr(self._sock,name)(*args)
error: [Errno 32] Broken pipe

 

This tells us a couple of important things:

 

(1)

 

The agent was able to make a TCP connection to the Host Monitor on port 9555 (the Host Monitor Listen Port).  After that, the communication was severed as the connection appears to have been dropped somewhere between the agent and the Host Monitor Server

 

(2)

 

This appears to happen frequently.

 

 

The agent will periodically capture host information and then upload that to the Host Monitor for indexing and storage.  The first place to look would be the Host Monitor log in /var/log/:

 

mgmt-cmf-mgmt-HOSTMONITOR*

 

You mentioned you could not find the error log but there is only the one log for all log information.

 

If you do not see anything wrong there, then we might need to employ more advanced diagnostics to determine what is happening.

No error messages.
I guess this issue is that I use Impala frequently. I reinstalled cluster today. At the beginning, the cluster was healthy. when I use Impala to load large amounts of data into kudu, the issue recurrence.
I think the reason may be caused by Impala generats a large number of logs that the agent cannot handle.I think one way is to increase the memory of the agent. Another way is whether there is a configuration to increase the processing capability of the agent side to the Impala log.I searched but not found how to fix. Could you give me some suggestion? Thanks.

@zy001,

 

I agree that it is possible (and even likely) that the issue is more on the agent side.  What we really need to see is what the agent is doing when at the time it is having trouble connecting.  A great way to have a peek at the internals is to send a SIGQUIT signal to the agent which will trigger it to dump thread stacks to the agent.  If you could run this a few times while CM is showing that the agent is out of contact with the host monitor, it might give us some clues if the agent is under stress at that time or not.

Oops... clicked "POST" before telling you how to get the agent to dump the thread stacks to the agent log.  You can run the following:

 

kill -SIGQUIT `cat /var/run/cloudera-scm-agent/cloudera-scm-agent.pid`

 

This will not cause the agent to restart or anything so it won't impact processing.

If you can run the kill -SIGQUIT a few times that would give us an idea of how the threads are progressing.

@bgooleyI ran this command.

Then the log in /var/log/cloudera-scm-agent/cloudera-scm-agent.log as follows:

Hi @AstroPratik ,

 

First, in order for us to provide the best help, we need to make sure we have information about the issue you are observing.  My guess is you are seeing the same health alert in Cloudera Manager, but we also need to confirm you are seeing the same messages in the agent log.

 

If so, please follow the instructions to provide a thread dump via the SIGQUIT signal.  The instructions I provided for the "kill -SIGQUIT" command only work in Cloudera Manager 5.x. If you are using CM 6, you can use the following:

kill -SIGQUIT $(systemctl show -p MainPID cloudera-scm-agent.service 2>/dev/null | cut -d= -f2)

 

If you do run the kill SIGQUIT make sure to run it a couple times so we can compare snapshots AND make sure you get the thread dump when the problem is occurring.

 

NOTE:  After reviewing the previous party's thread dump, it appears that a thread that is spawned to collect information for a diagnostic bundle is slow in processing; the thread that uploads service and host information to the Host and Service Monitor servers also seems to be slow.

 

Since the process of obtaining a diagnostic bundle is something that does not happen often, it is likely that the bundle creation is triggering the old event.

 

There are a number of possible causes for "firehose" trouble, though, so it is important that we understand the facts about your situation before making any judgements.
