当使用Java 11从弹性搜索5.0.1到NFS分区存储索引时，出现异常。

弹性搜索日志中的Stacktrace：

注意：相同的设置可以在Java8上正常工作

要回答有关Java版本的问题：

this thread中的讨论是说6.x版将支持Java 11。

Here是当前支持的Java版本的概述。 6.5.x版支持Java 11。

但异常是由弹性过程引起的，该过程很容易导致该异常过程对异常消息中的文件系统文件夹没有写权限：

<input id='search' type='search'><input type='button' value='search'>

<article id='content'>
  <p>Murphy, Kelly, O’Sullivan, Walsh, Smith, O’Brien, Byrne, Ryan, O’Connor, O’Neill, O’Reilly, Doyle, McCarthy, Gallagher, O’Doherty, Kennedy, Lynch, Murray, Quinn, Moore, McLoughlin, O’Carroll, Connolly, Daly, O’Connell, Wilson, Dunne, Brennan, Burke, Collins, Campbell, Clarke, Johnston, Hughes, O’Farrell, Fitzgerald, Brown, Martin, Maguire, Nolan, Flynn, Thompson, O’Callaghan, O’Donnell, Duffy, O’Mahony, Boyle, Healy, O’Shea, White, Sweeney, Hayes, Kavanagh, Power, McGrath, Moran, Brady, Stewart, Casey, Foley, Fitzpatrick, O’Leary, McDonnell, MacMahon, Donnelly, Regan, Donovan, Burns, Flanagan, Mullan, Barry, Kane, Robinson, Cunningham, Griffin, Kenny, Sheehan, Ward, Whelan, Lyons, Reid, Graham, Higgins, Cullen, Keane, King, Maher, MacKenna, Bell, Scott, Hogan, O’Keeffe, Magee, MacNamara, MacDonald, MacDermott, Molony, O’Rourke, Buckley, O’Dwyer</p>

请检查文件夹 / globalSearchElkData / nodes / 0

的权限
