500 status code received on GET method for API: /api/v1/stacks/HDP/versions/2.3/recommendations

[#1]

I restarted my Ambari based cluster and trying to navigate to any service I am getting this error

500 status codereceived on GET method for API: /api/v1/stacks/HDP/versions/2.3/recommendations

What can be possible reasons for this

[#2]

@Swapnil Prabhu what does the ambari server log say? I'd give it a bit of time and try again.

[#3 · Accepted solution]

This got resolved after I granted permission to /var/run/ambari-server

[#4]

@Swapnil Prabhu What do you mean by granting permission to /var/run/ambari-server ? Did you grant a particular user execute permission ? Please be more specific.

[#5]

Try: sudo chown -R ambari /var/run/ambari-server

Step 1: cat /etc/ambari-server/conf/ambari.properties | grep ambari-server.user.

Know the user from above command.

Step 2: change user /var/run/ambari-server

chown -R <output of above command> /var/run/ambari-server
