Hi I have a 4 node cluster and I can't seem to upgrade from CDH 5.5.2 to 5.9. It is getting stuck on upgrading Solr.

Here is the err file

I have chmodded the parent directory '

/run/cloudera-scm-agent/process/

to be 777 but it doesnt make sense why its not reading the file

supervisor.conf

anyway because the user is solr and solr is the owner of the file

Actually, this message may be showing us the cause. Due to the fact that the interesting bit was off the page when I was looking at your Zookeeper snippet, I couldn't see it at first:

2016-12-26 20:13:48,322 INFO org.apache.zookeeper.server.PrepRequestProcessor: Got user-level KeeperException when processing sessionid:0x1593c8f09d800f6 type:create cxid:0x2 zxid:0x1b2ea txntype:-1 reqpath:n/a Error Path:/solr Error:KeeperErrorCode = NoNode for /solr

Zookeeper appears to have no znode for /solr

To create one, in Cloudera Manager, Go to Solr.

Next, click on the Actions button (drop-down) on the far right and choose "Initialize Solr"

This will create the /solr znode.

After that, try starting Solr again.

Ben

bgooley · ‎12-24-2016

The problem occurs when trying to set the scheme to http for the Solr znode in Zookeeper:

name-node-1:2181/solr

Make sure that Zookeeper is running and that "name-node-1" can be resolved to an IP. You might check the zookeeper log to see if there were any errors. If not, it is more likely that a connection could not be made to zookeeper to update the scheme property.

Regards,

Ben

Thanks Ben,

I checked the Zookeeper logs there is not much help there

Zookeeper is running, name-node-1 resolves to an IP and zookeeper and solr-server are on the same node anyway. What could be going on?

I would verify resolution of the host to IP and make sure you can make a connection to zookeeper from the host on which you are trying to start Solr. If you are not seeing any error messages in Zookeeper logs, that is a basic indicator that a connection to the zookeeper could not be established. First thing to check is if you can connect from the same host, using the same IP/port, to the server.

Ben, the services are on the same host, and yes I already verified those things.

That did the trick thanks a lot!

Actually, this message may be showing us the cause. Due to the fact that the interesting bit was off the page when I was looking at your Zookeeper snippet, I couldn't see it at first:

2016-12-26 20:13:48,322 INFO org.apache.zookeeper.server.PrepRequestProcessor: Got user-level KeeperException when processing sessionid:0x1593c8f09d800f6 type:create cxid:0x2 zxid:0x1b2ea txntype:-1 reqpath:n/a Error Path:/solr Error:KeeperErrorCode = NoNode for /solr

Zookeeper appears to have no znode for /solr

To create one, in Cloudera Manager, Go to Solr.

Next, click on the Actions button (drop-down) on the far right and choose "Initialize Solr"

This will create the /solr znode.

After that, try starting Solr again.

Regards,

Ben

Ok I will try the initialize Solr. Thanks for the idea Ben! I will try it as son as I get to another office. I can't do it from the current client as their firewalls are pretty tight and I have it in GCE, but I'm excited to try this.
