version.pngversion-2.pngversion-1.pngHi,
I have recently innstalled HDP 2.6 but as our application was not supporting, we had to uninstall it and install 2.5. All was working fine but now my HDP version is pointing to 2.6 and all services are not starting.

I was able to start the services one by one instead of starting all at once but again when i tried to restart the services all at a time the issue has come up again.

Can you check by running
ls -al /usr/hdp/current
All the components should point to the corect 2.5 version like below
/usr/hdp/current ranger-usersync -> /usr/hdp/2.5.x.x/ranger-usersync
The links should point to the 2.5 packages

All are showing correct link.

Please provide out of below directory, It should have current and version only.
If 2.6 Directory exit, kinldy remove and start the services ?
