i can't add the flow config in elasticsearch.yml `thread_pool:` `percolate:` `size: 16` `queue_size: 2000` the error is ``` **[2017-08-04T11:40:26,843][WARN][o.e.b.ElasticsearchUncaughtExceptionHandler] [node-1] uncaught exception in thread [main]** **org.elasticsearch.bootstrap.StartupException: java.lang.IllegalArgumentException: unknown setting [thread_pool.percolate.size] did you mean any of [thread_pool.get.size, thread_pool.search.size, thread_pool.force_merge.size]?** ``` \*\* at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:127) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.bootstrap.Elasticsearch.execute(Elasticsearch.java:114) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.cli.EnvironmentAwareCommand.execute(EnvironmentAwareCommand.java:67) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.cli.Command.mainWithoutErrorHandling(Command.java:122) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.cli.Command.main(Command.java:88) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:91) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:84) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* `**Caused by: java.lang.IllegalArgumentException: unknown setting [thread_pool.percolate.size] did you mean any of [thread_pool.get.size, thread_pool.search.size, thread_pool.force_merge.size]?**` \*\* at org.elasticsearch.common.settings.AbstractScopedSettings.validate(AbstractScopedSettings.java:293) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.common.settings.AbstractScopedSettings.validate(AbstractScopedSettings.java:256) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.common.settings.SettingsModule.(SettingsModule.java:139) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.node.Node.(Node.java:343) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.node.Node.(Node.java:242) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.bootstrap.Bootstrap$5.(Bootstrap.java:232) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.bootstrap.Bootstrap.setup(Bootstrap.java:232) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.bootstrap.Bootstrap.init(Bootstrap.java:350) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* at org.elasticsearch.bootstrap.Elasticsearch.init(Elasticsearch.java:123) ~[elasticsearch-5.4.2.jar:5.4.2]\*\* \*\* ... 6 more\*\* percolate For percolate operations.

and what this Meaning **refresh** **For refresh operations. Thread pool type is scaling with a keep-alive of 5m and a max of min(10, (# of available processors)/2).** if cpu is 8 core, the min is 32 the max is 32\*(104)? ---

Please format your code using `` icon as explained in [this guide](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will make your post more readable. Or use markdown style like: ```` ``` CODE ``` ```` Wrong yml format here I think. Missing indentation? ---
