我有,我認爲是一樣的,這裏所描述的問題:錯誤打開Lucene索引時:產生java.io.IOException:地圖失敗
Error when opening a lucene index: Map failed
但是該解決方案並不在此申請所以我提供了更多的細節,並再次詢問。
IndexReader indexReader = DirectoryReader.open(FSDirectory.open(Paths.get("the_path")));
異常堆棧跟蹤是:
該指數是使用的Solr 5.3
的代碼產生例外的線是創建
Exception in thread "main" java.io.IOException: Map failed: MMapIndexInput(path="/mnt/fastdata/ac1zz/JATE/solr-5.3.0/server/solr/jate/data_aclrd/index/_5t.tvd") [this may be caused by lack of enough unfragmented virtual address space or too restrictive virtual memory limits enforced by the operating system, preventing us to map a chunk of 434505698 bytes. Please review 'ulimit -v', 'ulimit -m' (both should return 'unlimited'), and 'sysctl vm.max_map_count'. More information: http://blog.thetaphi.de/2012/07/use-lucenes-mmapdirectory-on-64bit.html]

所建議的解決方案,在異常消息在這種情況下不起作用,因爲我正在服務器上運行應用程序,並且我沒有更改這些應用程序的權限。
即,
ulimit -v unlimited
打印: 「-bash:的ulimit:虛擬存儲器:不能修改限制:操作不允許」
和 的sysctl -w vm.max_map_count =千萬
給出:「錯誤:關鍵'vm.max_map_count'的權限被拒絕'」
有沒有反正我可以解決這個問題?
謝謝
聽起來像什麼,你應該問的是:爲什麼的ulimit是給你「操作不允許」(http://unix.stackexchange.com/questions/31679/ulimit -pickle-操作不許可和 - 命令未找到) – femtoRgon
