Dear Experts,

I installed HDF (nifi-1.1.1.0-12) using a user nifi (group hadoop) under /opt/nifi-1.1.1.0-12

Starting/Stopping the nifi service from bash works fine.

Afterwards I installed the Ambari Service for Nifi as outlined on https://github.com/abajwa-hw/ambari-nifi-service

Unfortunately whenever I start Nifi under Ambari it goes down without showing an error in '/var/lib/ambari-agent/data/errors-xxxx.txt'

the stout of ambari looks like the following:

---------------------------

Again, when I start nifi from bash it works as expacted.

Any help on how to fix this or better trace the problem is highly appreciated!

@Rainer Geissendoerfer Others have encountered similar issues with the Nifi service (usually on Java 😎 as well but I have not been able to consistently reproduce it yet. From what I have seen of this issue, if you run the steps to start Nifi manually via CLI, it works (but for some reason not from Ambari). You can try below manual commands to start Nifi and populate the pid file so that Ambari can track its status:

su - nifi
export JAVA_HOME=/usr/java/default
/opt/nifi-1.1.1.0-12/bin/nifi.sh start >> /var/log/nifi/nifi-setup.log
cat /opt/nifi-1.1.1.0-12/bin/nifi.pid | grep pid | sed 's/pid=\(\.*\)/\1/' > /var/run/nifi/nifi.pid
#run below as root
chown nifi:nifi /var/run/nifi/nifi.pid

If you are encountering the same issue, could you provide the below details so we can try to reproduce it:

java version
OS/version
Ambari + HDP version (is this sandbox?)
are you installing Nifi service on same node as Ambari?

aervits · ‎01-30-2016

@Rainer Geissendoerfer please paste the nifi logs in n /var/log/nifi

rainer_geissend · ‎01-30-2016

Based on Neerjas comment below I enabled user nifi to write into /var/log/ ... no at least I am getting an error in the Ambari Console when starting the service that I attached in errors-1795.txt.

In addition I posted the logs of /var/log/nifi.

Again, when I am starting "nifi.sh start" from bash, nifi starts successfully.

Thanks, in advance, for any further advise.

br,

Rainer

@Rainer Geissendoerfer

Couple of things:

1) Ambari service for NiFi is not officially released yet. You are using git code.

2) This is based on existing issue. I don't know how your setup looks like so you may want to check this.

In git code, user nifi is starting nifi ..make sure that nifi user has privilieges to write to /var/log

rainer_geissend · ‎01-30-2016

Hi Neeray, thanks for your feedback ... I am now getting more detailed logs ... even though the problem didn't go aways, please see above. Thanks, Rainer

nsabharwal · ‎01-30-2016

@Rainer Geissendoerfer If you look deeply 😉 it's still permission issue. Make sure that you create directories for nifi user under /var/log, /var/run etc.

nsabharwal · ‎01-30-2016

@Rainer Geissendoerfer You can search git code to get an idea on directory structure

nsabharwal · ‎02-12-2016

@Rainer Geissendoerfer Could you please accept the best the answer to close this thread?

aervits · ‎01-30-2016

@Rainer Geissendoerfer create directory /var/run/nifi and make sure permissions are set correctly on the directory

rainer_geissend · ‎01-30-2016

I did that already in order to trick Ambari after starting nifi through bash (and then I inserted a valid PID in /var/run/nifi) and restarted the service through Amari. Obviously Ambari found that PID and got green ... but still no luck starting the service through Ambari 😞

aervits · ‎01-30-2016

Lets do one thing at a time. Stop the version initiated with bash. Clean up the pid and let Ambari start the service and watch for new errors. @Rainer Geissendoerfer

rainer_geissend · ‎01-30-2016

I think I am messing up things here 🙂 ... I initially put the user nifi in the groop hadoop ... and did the nifi install ... as what it looks like ambari requires user "nifi" to be in group "nifi" ... I will start to change a couple of access rights and provide further feedback when it's done ...

rainer_geissend · ‎01-30-2016

OK ... here is where I am ... I changed my primary group of user nifi to nifi ... i stopped nifi through "nifi.sh stop"

I cleared /var/log/nifi and /var/run/nifi

when I start nifi now from ambari there is nothing in stderr and I get the following feedback in ambari:

stderr: /var/lib/ambari-agent/data/errors-1806.txt

None

Still though the service goes down after some green blinking ... when I am going to bash there is also no nifi service running ...

in /var/log/nifi there are 4 log files

nifi-app.log nifi-bootstrap.log nifi-setup.log nifi-user.log

from bash the service goes up.

... and I am getting crazy 🙂

Any Advise???

@Rainer Geissendoerfer

You can try this

Delete the service

run this in ambari server

curl --user admin:admin -i -H "X-Requested-By: ambari" -X DELETE http://`hostname -f`:8080/api/v1/clusters/clustername/services/NIFI

cleanup everything under /var/log/nifi and /var/run/nifi

and try to add it back using Ambari after making sure that nifi directory exists under /var/log and /var/run with proper permissions

or

Wait for the official release of Amabri Service. 🙂

nsabharwal · ‎01-30-2016

@Rainer Geissendoerfer You may have to run this before deleting in case delete complains

In Ambari server

curl --user admin:admin -i -H "X-Requested-By: ambari" -X PUT http://`hostname -f`:8080/api/v1/clusters/HDPTEST/services/NIFI -d '{"RequestInfo": {"context" :"Stop NIFI via REST"}, "Body": {"ServiceInfo": {"state": "INSTALLED"}}}'

What group does /var/run/nifi belong to? @Rainer Geissendoerfer I suggest doing everything from scratch only with Ambari service and new copy of sandbox

abajwa · ‎01-30-2016

@Rainer Geissendoerfer Others have encountered similar issues with the Nifi service (usually on Java 😎 as well but I have not been able to consistently reproduce it yet. From what I have seen of this issue, if you run the steps to start Nifi manually via CLI, it works (but for some reason not from Ambari). You can try below manual commands to start Nifi and populate the pid file so that Ambari can track its status:

su - nifi
export JAVA_HOME=/usr/java/default
/opt/nifi-1.1.1.0-12/bin/nifi.sh start >> /var/log/nifi/nifi-setup.log
cat /opt/nifi-1.1.1.0-12/bin/nifi.pid | grep pid | sed 's/pid=\(\.*\)/\1/' > /var/run/nifi/nifi.pid
#run below as root
chown nifi:nifi /var/run/nifi/nifi.pid

If you are encountering the same issue, could you provide the below details so we can try to reproduce it:

java version
OS/version
Ambari + HDP version (is this sandbox?)
are you installing Nifi service on same node as Ambari?

henrysowell · ‎01-31-2016

I've experienced the same issue on three different installs, Centos 6 & 6.5, Java 8, HDP 2.3.2 & 2.3.4, sandbox and cluster. On the clusters I was installing NiFi on a separate node.

abajwa · ‎02-01-2016

@Henry Sowell could you check that on the node where Nifi is setup, the java location Ambari is starting Nifi with (usually /usr/java/default) exists and has the appropriate version of java?

nsabharwal · ‎02-01-2016

@Rainer Geissendoerfer

I am experiencing the same issue in my cluster. I chose to stick with manual setup and wait for the offical release of ambari service.
