https://issues.apache.org/jira/browse/SOLR-17754 # Description Stuck overseer that sometimes happens under high load, when the overseer has at least 100 running tasks. See [Jira](https://issues.apache.org/jira/browse/SOLR-17754) for the full scenario as description is pretty long. # Solution This fixes the overseer main loop so we never submit more than 100 concurrent tasks to the thread pool. Instead of manually tracking when a task is complete, we check the status using a standard java `Future`. The changes also makes sure we don't write the result to ZK response node when we should not (see [comment](https://issues.apache.org/jira/browse/SOLR-17754?focusedCommentId=17951216&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17951216)), removing the erroneous occurrences of log `"Response ZK path: <node> doesn't exist. Requestor may have disconnected from ZooKeeper"` # Tests Add a new test to make sure we don't fail anymore with lot of tasks. -- This is an automated message from the Apache Git Service.
