Solrサービス起動エラー:Path must not end with/character
今日、初めてSolrのUI Consoleに対してAdd Core操作を行ったとき、デフォルトのオプションを使用して、コミット後のページは反応しませんでしたが、Solrのログは次のようなログを大量に放出しました.
— Creating cores using the web UI with default values causes the system to become unresponsive
You can use the Solr Server web UI to create new cores. If you click Create Core without making any changes to the default attributes, the server may become unresponsive. Checking the log for the server shows a repeated error that begins:
Bug: Solr-5813
Severity: Medium
Workaround: To avoid this issue, do not create cores without first updating values for the new core in the web UI. For example, you might enter a new name for the core to be created.
If you created a core with default settings and are seeing this error, you can address the problem by finding which node is having problems and removing that node. Find the problematic node by using a tool that can inspect ZooKeeper, such as the Solr Admin UI. Using such a tool, examine items in the ZooKeeper queue, reviewing the properties for the item. The problematic node will have an item in its queue with the property collection="".
Remove the node with the item with the collection="" property using a ZooKeeper management tool. For example, you can remove nodes using the ZooKeeper command line tool or recent versions of HUE.
