Ambari unable to run custom hook for modifying user hive

rvillanueva — Tue, 26 Nov 2019 04:13:44 GMT

Attempting to add a client node to cluster via Ambari (v2.7.3.0) (HDP 3.1.0.0-78) and seeing odd error

The problem appears to be

caused by

Though, when running

[root@HW001 .ssh]# /usr/bin/hdp-select versions3.1.0.0-78

from the ambari server node, I can see the command runs.

Looking at what the hook script is trying to run/access, I see

notice there is ls: cannot access /var/lib/ambari-agent/data/structured-out-632.json: No such file or directory. Not sure if this is normal, though.

Anyone know what could be causing this or any debugging hints from this point?

Adding some log printing lines near the offending final line in the error trace, ie. File "/usr/lib/ambari-agent/lib/resource_management/libraries/functions/stack_select.py", line 147, in get_supported_packages, I print the code and stdout:

2
ambari-python-wrap: can't open file '/usr/bin/hdp-select': [Errno 2] No such file or directory

So what the heck? It wants hdp-select to already be there, but ambari add-host UI complains if I manually install that binary myself beforehand. When I do manually install it (using the same repo file as in the rest of the existing cluster nodes) all I see is...

Re: Ambari unable to run custom hook for modifying user hive

rvillanueva — Tue, 26 Nov 2019 21:21:48 GMT

After just giving in and trying to manually create the hive user myself, I see

[root@airflowetl ~]# useradd -g hadoop -s /bin/bash hive useradd: user 'hive' already exists [root@airflowetl ~]# cat /etc/passwd | grep hive [root@airflowetl ~]# id hive uid=379022825(hive) gid=379000513(domain users) groups=379000513(domain users)

The fact that this existing user's uid looks like this and is not in the /etc/passwd file made me think that there is some existing Active Directory user (which this client node syncs with via installed SSSD) that already has the name hive. Checking our AD users, this turned out to be true.

Temporarily stopping the SSSD service to stop sync with AD (service sssd stop) (since, not sure if you can get a server to ignore AD syncs on an individual user basis) before rerunning the client host add in Ambari fixed the problem for me.

I was facing the similar error and got it resolved by added Hadoop users to passwd file.
