索引后锁定的文件 [英] Files locked after indexing

问题描述

我的(网络)应用程序中具有以下工作流程:

I have the following workflow in my (web)application:

• 从档案中下载pdf文件
• 为文件编制索引
• 删除文件

我的问题是，在对文件建立索引之后，它保持锁定状态，而删除部分会引发异常.

My problem is that after indexing the file, it remains locked and the delete-part throws an exception.

这是我为文件建立索引的代码段:

Here is my code-snippet for indexing the file:

try
{
   ContentStreamUpdateRequest req = new ContentStreamUpdateRequest("/update/extract");
   req.addFile(file, type);
   req.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);

   NamedList<Object> result = server.request(req);

   Assert.assertEquals(0, ((NamedList<?>) result.get("responseHeader")).get("status"));
}

我想念什么吗?

我也尝试过这种方法，但是结果相同...

I tried this way too, but with the same result...

ContentStream contentStream = null;

    try
    {
      contentStream = new ContentStreamBase.FileStream(document);

      ContentStreamUpdateRequest req = new ContentStreamUpdateRequest(UPDATE_EXTRACT_REQUEST);
//      req.addFile(document, context.getProperty(FTSConstants.CONTENT_TYPE_APPLICATION_PDF));
      req.addContentStream(contentStream);
      req.setAction(AbstractUpdateRequest.ACTION.COMMIT, true, true);

      NamedList<Object> result = server.request(req);

      if (!((NamedList<?>) result.get("responseHeader")).get("status").equals(0))
      {
        throw new IDSystemException(LOG, "Document could not be indexed. Status returned: " +
                                         ((NamedList<?>) result.get("responseHeader")).get("status"));
      }
    }
    catch (FileNotFoundException fnfe)
    {
      throw new IDSystemException(LOG, fnfe.getMessage(), fnfe);
    }
    catch (IOException ioe)
    {
      throw new IDSystemException(LOG, ioe.getMessage(), ioe);
    }
    catch (SolrServerException sse)
    {
      throw new IDSystemException(LOG, sse.getMessage(), sse);
    }
    finally
    {
      try
      {
        if(contentStream != null && contentStream.getStream() != null)
        {
          contentStream.getStream().close();
        }
      }
      catch (IOException ioe)
      {
        throw new IDSystemException(LOG, ioe.getMessage(), ioe);
      }
    }

推荐答案

这似乎是一个错误

在此建议一个补丁 https://issues.apache.org/jira/browse/SOLR-1744

也结帐 http://lucene.472066.n3 .nabble.com/ContentStreamUpdateRequest-addFile-fails-to-close-Stream-td485429.html

您可以检查流是否不为空，然后将其关闭.

you can check if the stream is not null and close it.
