Starting Solr on Ambari

Rising Star

Hi,

I installed Solr on Amabari (HDP2.5) on AWS. Amabri console shows that it is stopped and when i want to start Sorl is says that it is already running. Also i can see the process is running.

How can i make its status on amabri running too?

Thanks,

SJ

Do you see a PID file in the directory "/var/run/solr/" If yes then try deleting it and then restart the solr. Then check again from ambari.

Hi,

No there is no PID under /var/run/solr but still the state of Solr in amabari is stopped.

Do you have Ambari Infra running on the same node as where you installed the Solr service?

Try this: list the solr process (ps -ef | grep ^infra) and find its process ID, let's say PID=3579, then do

su - infra-solr  -c 'echo 3579 > /var/run/ambari-infra-solr/solr-8886.pid'

Then wait a few moments, and Ambari will show Solr as running. After that you can try to restart Solr, and everything should be fine. By the way, solr-8886 means Solr running on port 8886.

@Sanaz Janbakhsh Is there a lock file in your index directory(s)? Solr may not start if there's a lock file. There's an option in Ambari 2.5 for Solr to delete the lock file before starting. There are pros and cons to this, but if you're starting all instances it is probably safe.
