Metrics monitor not starting in HDP 2.5

Getting the following error.

Strange part is that metrics monitor startup script is using python2.7 but 2.6 site-packages are being looked at. Is that expected? I tried exporting `PYTHON=/usr/bin/python2.6` in ams-env which resulted in metrics monitor failure saying > python 2.6 is needed.

I have tried https://community.hortonworks.com/questions/26665/ambari-metrics-monitor-not-starting-importerror-ca... but that didn't help either.

Try this: cd /usr/lib/python2.6/site-packages/resource_monitoring/psutil

make install ambari-metrics-monitor restart

Thanks @Mugdha, it worked 🙂
