Mine patch= solve those issues and integrate both filesystems such a way that most of = the core functionality is common for both and therefore simplifying the mai= ntainability. > The core features: > * Support for HTTP/SOCKS proxies > * Support for passive FTP > * Support for explicit FTPS (SSL/TLS) > * Support of connection pooling - new connection is not created for ever= y single command but reused from the pool. > For huge number of files it shows order of magnitude performance improve= ment over not pooled connections. > * Caching of directory trees. For ftp you always need to list whole dire= ctory whenever you ask information about particular file. > Again for huge number of files it shows order of magnitude performance i= mprovement over not cached connections. > * Support of keep alive (NOOP) messages to avoid connection drops > * Support for Unix style or regexp wildcard glob - useful for listing a = particular files across whole directory tree > * Support for reestablishing broken ftp data transfers - can happen surp= risingly often > * Support for sftp private keys (including pass phrase) > * Support for keeping passwords, private keys and pass phrase in the jce= ks key stores -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
