我在让HttpFS与SSL配合使用方面遇到问题。我正在使用的hadoop版本是2.6.5。
我尝试使用环境变量HTTPFS_SSL_KEYSTORE_FILE，HTTPFS_SSL_KEYSTORE_PASS和HTTPFS_SSL_ENABLED，发现使用了值并将它们添加到CATALINA_OPS中。此Hadoop版本仍然需要配置env变量。我遵循了互联网上的指南。
但是在后面的部分中，该配置将被完全忽略，并且HttpFS可以在HTTP中运行而无需进行任何加密：
usage: java org.apache.catalina.startup.Catalina [ -config {pathname} ] [ -nonaming ] { -help | start | stop }

如您所见，SSL配置被完全忽略。
如何真正为HttpFS启用SSL / TLS？
