Question

我尝试在几秒钟内创建一个索引，我得到了这个：

[2014-06-02 14:10:14,414][WARN ][index.engine.internal    ] [shardicaprio] [myindex][0] Could not lock IndexWriter isLocked [false]

这里是完整的堆栈跟踪：

我没有内存重载，我的heapsize很好，但CPU。 CPU过载甚至超过100％的使用率。我试图恢复索引，删除索引，重新创建索引但每次都告诉同样的事情。我无法弄清楚导致这种情况的原因。

有什么想法吗？

Answer 1

由于我已将此行添加到elasticsearch中，因此我没有再遇到此问题。

index.store.fs.lock: none

我认为这是由elasticsearch的文件系统锁定引起的。如果我说Elasticsearch实例不会锁定存储文件系统，则不会发生。

无法锁定IndexWriter isLocked [false]
