Lucene 无法锁定IndexWriter isLocked[错误]

我试图在几秒钟内创建一个索引，结果如下：

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

下面是完整的堆栈跟踪：

我没有内存过载，我的heapsize很好，但是CPU。CPU过载甚至超过使用率的100%。我试着恢复索引、删除索引、重新创建索引，但每次都是这样。我想不出是什么原因造成的

---

有什么想法吗？

我没有再面对这个问题，因为我在elasticsearch中添加了这条线

index.store.fs.lock: none

---

我认为这是由elasticsearch的文件系统锁定造成的。如果我说Elasticsearch实例不锁定存储文件系统，它不会发生。

路径

/var/lib/Elasticsearch/data/shardicaprio/nodes/0/index/myindex/0/index

对您来说合适吗？elasticsearch是否具有写入权限？是的。路径正确，ES对其拥有完全权限。它不断地创建索引，它们很好。我上面定义的一个“索引”就导致了这个异常。我认为您的服务器上运行着两个实例。。你能检查一下吗。Ps ef | grep elasticNope@BlackPOP，当然我只运行一个实例一个节点单碎片。它是一个已经安装的centos 32位oracle jvm。我不明白。。。如果elasticsearch无法获得FS锁，它将如何写入FS中的文件？
