在Hue页面上传大文件失败

问题

通过Hue页面上传大文件时，上传失败。

回答

1. 不建议使用Hue文件浏览器上传大文件，大文件建议使用客户端通过命令上传。
2. 如果必须使用Hue上传，参考以下步骤修改Httpd的参数：
   1. 以omm用户登录主管理节点。
   2. 执行以下命令编辑“httpd.conf”配置文件。

      vi $BIGDATA_HOME/om-server/Apache-httpd-*/conf/httpd.conf

   3. 搜索21201，在</VirtualHost>配置中加上“RequestReadTimeout handshake=0 header=0 body=0”，如下所示。

      ...
      <VirtualHost *:21201>
          ServerName https://10.112.16.93:21201
          AllowEncodedSlashes On
          SSLProxyEngine On
          ProxyRequests Off
          TraceEnable off
          ProxyTimeout  1200
          RewriteEngine on
          RewriteMap proxylist dbm:${BIGDATA_ROOT_HOME}/om-server_*/Apache-httpd-*/conf/proxylist.dbm
      
          RewriteRule ^(\/.*)$  ${proxylist:/Hue/Hue/21201}$1 [E=TARGET_PATH:$1,L,P]
      
          Header edit Location ^(?!https://10.112.16.93:20009|https://10.112.16.93:21201)http[s]?://[^/]*(.*)$  https://10.112.16.93:21201$1
      
          ProxyPassReverseCookiePath / / interpolate
      
          SSLEngine On
          SSLProxyProtocol  All +TLSv1.2 -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
          SSLProtocol ALL +TLSv1.2 -SSLv2 -SSLv3 -TLSv1 -TLSv1.1

          SSLProxyCheckPeerName off
          SSLProxyCheckPeerCN off
          SSLCertificateFile "${BIGDATA_ROOT_HOME}/om-server_*/Apache-httpd-*/conf/security/proxy_ssl.cert"
          SSLCertificateKeyFile "${BIGDATA_ROOT_HOME}/om-server_*/Apache-httpd-*/conf/security/server.key"
          SSLProxyCACertificateFile ${BIGDATA_ROOT_HOME}/om-server_*/apache-tomcat-*/conf/security/tomcat.crt
          SSLCertificateChainFile "${BIGDATA_ROOT_HOME}/om-server_*/Apache-httpd-2.4.39/conf/security/proxy_chain.cert"
          RequestReadTimeout handshake=0 header=0 body=0
      </VirtualHost>
      ...

   4. 执行pkill -9 httpd命令结束httpd进程，并等待自动重启httpd。
