basically these node machines just install DataNode, impala, node manager, no others. I have changed impala log to WARN level, if this issue still happened then I will change other DataNode and node manager log level. hope can find out root cause . anything good and bad news will feed back to you , thanks.

Hi, after set the parameter "-max_cached_file_handles=0 " as your workaround shows me, I got another issue, it's agent heartbeat timeout. the ticket URL as below: <a href="https://community.cloudera.com/t5/Support-Questions/Cloudera-Manager-agent-bad-healthy/m-p/283865#M210854" target="_blank">https://community.cloudera.com/t5/Support-Questions/Cloudera-Manager-agent-bad-healthy/m-p/283865#M210854</a> My CDH env has been online more than half year, agent heartbeat timeout has never been happened, but after comparing the date of setting the impala parameter and agent heartbeat issue date , it seems there are connection, but I am not sure . what I mean is the agent heartbeat timeout issue happened after I set the impala parameter "-max_cached_file_handles=0 ". is that impossible ?

today I continue to troubleshooting this issue since there are two servers happened this issue. I always ask myself one question: what's difference between normal server and ab-normal server ? 1) the ab-normal server agent logs show me: heartbeat took long time 40-100s, even more, but the other servers took a little time: ~10s so why the ab-normal server took so long time to send heartbeat? ab-normal server agent cpu usage: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

I have inspected many times in CM, it's failed if the machine happened this issue. then I run the network performance script manually, it's success. that's very strange. the script is: /opt/cloudera/cm-agent/service/perf/host_perf_diag.py "input.json" "/tmp/result.json" the above command is copied from CM, as we know CM will show the command when network inspecting. so what's the diff between CM inspect and manual inspect ?

there are 5 machines happened this issue recently, agent took long time to contact monitor server. and it's fine after I restart agent. one thing I can sure resource usage is low, so I think there are other reasons . the below is healthy graph history , every time this issue happened I was going to check the monitor logs, host monitor, service monitor, but find nothing. then, I am going to using Cloudera Manager network performance tools to check , it's failed on these server. but why failed? could you give me some advises how to find root cause this kind issue ? is it because network ?

my CDH Cluster has been online more than half year, all the machines and service is normal.
but recently , there is one host agent always under bad healthy, and Cloudera Manager will show the red color on this host.
then I check the agent log as below:

I am going to check the server cpu load and other things, it seems nothing happened. then I restart agent, but it will happen hours later or one day later , so my questions is:
1) how this error happened ?
thanks
