本文整理了Java中org.elasticsearch.cluster.metadata.IndexMetaData.isOnSharedFilesystem()方法的一些代码示例，展示了IndexMetaData.isOnSharedFilesystem()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。IndexMetaData.isOnSharedFilesystem()方法的具体详情如下：
包路径：org.elasticsearch.cluster.metadata.IndexMetaData
类名称：IndexMetaData
方法名：isOnSharedFilesystem

IndexMetaData.isOnSharedFilesystem介绍

[英]Returns true iff the given settings indicate that the index associated with these settings allocates it's shards on a shared filesystem. Otherwise false. The default setting for this is the returned value from #isIndexUsingShadowReplicas(org.elasticsearch.common.settings.Settings).
[中]如果给定设置指示与这些设置关联的索引在共享文件系统上分配其碎片，则返回true。否则false。默认设置是#isindexusingshadowreplications（org.elasticsearch.common.settings.settings）返回的值。
