ambari-metrics-monitor not starting. ImportError: cannot import name _common

[#1]

I have 7 nodes configured as follows: 3 MasterNodes, 1 AdminNode 3 DataNodes. The ambari-metrics-monitor is starting fine in the DataNodes but for the rest of nodes is throwing the following error:

 from metric_collector import MetricsCollector
  File "/usr/lib/python2.6/site-packages/resource_monitoring/core/metric_collector.py", line 23, in <module>
    from host_info import HostInfo
  File "/usr/lib/python2.6/site-packages/resource_monitoring/core/host_info.py", line 22, in <module>
    import psutil
  File "/usr/lib/python2.6/site-packages/resource_monitoring/psutil/build/lib.linux-x86_64-2.6/psutil/__init__.py", line 89, in <module>
    import psutil._pslinux as _psplatform
  File "/usr/lib/python2.6/site-packages/resource_monitoring/psutil/build/lib.linux-x86_64-2.6/psutil/_pslinux.py", line 20, in <module>
    from psutil import _common
ImportError: cannot import name _common

I have uninstalled and installed again the ambari-metrics-monitor with no success. Any thoughts or alternatives to solve this problem??

I have a single Python v2.2.6 in all nodes. HDP 2.4. Ambari 2.2.1

[#2 · Accepted solution]

I saw this, and I think it's fixed in latest Ambari versions. Can you try:

cd /usr/lib/python2.6/site-packages/resource_monitoring/
python psutil/build.py

and restart metrics monitors.

This worked just fine!! Thanks @Predrag Minovic!

[#4]

Thank you it worked 🙂 @Predrag Minovic

As am just starting on Ambari and HDP

Kindly shed some light on what was the problem about and how can it be avoided in future?

@Predrag Minovic. I also had same issue and I tried to apply your given workaround but it failed with following error.

[ams@server resource_monitoring]$ python psutil/build.py

When I checked given build.out file it gave me following output. So Can you please help me to resolve it.

Hello Guys,

I used a RHEL 7 and I have Python 2.7 and this is not building the psutils.

Is there any workaround ?

Best regards
