Solr service check fails if NN HA is enabled with error "Unable to create core [collection1_shard2_replica1] Caused by: Connection refused"

[#1]

Issue:

Solr service check fails from ambari when Namenode HA is enabled with error:

Unable to create core [collection1_shard2_replica1] Caused by: Connection refused

Solution 1:

add this line "SOLR_HDFS_CONFIG=/etc/hadoop/conf" to solr-config-env content at the end of file

Restart Solr and now the service checks should pass.

Solution 2:

Another workaround is to edit the following file on your Ambari Server: /var/lib/ambari-server/resources/mpacks/solr-ambari-mpack-5.5.2.2.5/common-services/SOLR/5.5.2.2.5/package/scripts/solr.py, and then make this change: https://github.com/lucidworks/solr-stack/commit/7b79894b37b862b86d80c64b34230bc9fed6e54a.

Then restart the Ambari Server. With this change in place the Solr instances will be started and will work fine with NN HA.

This will be fixed in HDP 2.6
