Error installing Slider Client using Ambari

[#1]

I got following errors when setup a 3 node cluster using Ambari (Ubuntu 16.04). It is reference content from /usr/hdp/current/slider-client/lib, which I don't have. In /usr/hdp/current/slider-client directory, I only have conf. This issue seems had been reported earlier, but I did not see the solution.

It looks like a Symlink issue. Looks like due to some reason the symlink is not created properly. The "lib" should be actually here

# ls -l /usr/hdp/2.6.5.0-292/slider/lib/

.

The "/usr/hdp/current/slider-client" path should be ideally a symlink something like following:

# ls -l /usr/hdp/current/slider-client
lrwxrwxrwx. 1 root root 27 Jun 28 22:44 /usr/hdp/current/slider-client -> /usr/hdp/2.6.5.0-292/slider

NOTE: here the version "2.6.5.0-292" might be different based on your Stack version. So please change the version accordingly.
.

So you might want to create a symlink on your own.
First if you have "slider-client" as a Directory or as a Symlink?

# ls -ld /usr/hdp/current/slider-client
lrwxrwxrwx. 1 root root 27 Jun 28 22:44 /usr/hdp/current/slider-client -> /usr/hdp/2.6.5.0-292/slider

If you find that "/usr/hdp/current/slider-client" is a directory then move it.

# mv /usr/hdp/current/slider-client  /usr/hdp/current/slider-client_OLD

Then create a symlink instead like:

# ln -s /usr/hdp/2.6.5.0-292/slider /usr/hdp/current/slider-client

NOTE: here the version "2.6.5.0-292" might be different based on your Stack version. So please change the version accordingly.
