Could not determine stack version for component nifi by calling '/usr/bin/hdp-select status nifi

Hi guys,

I've been trying to install SAM TP2 on an existing 2.6 cluster I have (I'll need to replicate the same on a customer's POC env)

Getting the following error on Install of NiFi

2017-05-05 17:09:31,122 - Could not determine stack version for component nifi by calling '/usr/bin/hdp-select status nifi > /tmp/tmpEy4hbD'. Return Code: 1, Output: ERROR: Invalid package - nifi

resource_management.core.exceptions.Fail: Applying File['/usr/hdp/current/nifi/bin/nifi-env.sh'] failed, parent directory /usr/hdp/current/nifi/bin doesn't exist

I think this is the relevant bit:

resource_management.core.exceptions.Fail: Applying File['/usr/hdp/current/nifi/bin/nifi-env.sh'] failed, parent directory /usr/hdp/current/nifi/bin doesn't exist

Then if i create the symbolic link as follows:

ln -s /usr/hdf/3.0.0.0-264/nifi/ /usr/hdp/current/nifi

I get:

resource_management.core.exceptions.Fail: Applying Directory['/usr/hdp/current/nifi/conf'] failed, looped symbolic links found while resolving /usr/hdp/current/nifi/conf

So clearly that's not right... I must have gone wrong somewhere, but where? Interestingly Registry and Streaming Analytics Manager itself install fine??? odd

Thanks in advance!

FINAL EDIT: Turns out this is expected because you need HDP 2.6.1 and Ambari 2.5.1 to make this work. Solved!

Fixed it lol. Turns out there was already a nifi dir in current which contains a conf and a lib. So i just had to link the bin??

ln -s /usr/hdf/3.0.0.0-264/nifi/bin /usr/hdp/current/nifi/bin

Then I get this and the install succeeds:

[root@ana-smartsense14test0 current]# ll /usr/hdp/current/nifi/
total 8
lrwxrwxrwx. 1 nifi nifi   29 May  5 18:10 bin -> /usr/hdf/3.0.0.0-264/nifi/bin
drwxr-xr-x. 2 nifi nifi 4096 May  5 18:10 conf
drwxr-xr-x. 2 nifi nifi 4096 May  5 18:09 lib

Doesn't seem correct - is this a bug or was it pibkac?

EDIT: I thought I fixed it, but Ambari is behaving oddly. NiFi starts and shows green, but no process is actually running on the machine. There's no pid file in /var/run/nifi and no logs are generated for nifi, meaning it never started. Manually running the sh script gives me this error:

[nifi@ana-smartsense14test0 bin]$ ./nifi.sh start
