[jira] [Updated] (FLUME-2409) NettyAvroRpcClient performs unnecessary hostname lookups

["Johny Rufus (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLUME-2409?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Johny Rufus updated FLUME-2409:
-------------------------------

    Attachment: FLUME-2409.patch

getHostString() is public only from JDK7, so we can use the InetSocketAddress toString() method, which essentially calls the InetAddress toString(), that prints the hostname, ip and port (and does not do the reverse lookup if hostname is not available)

> When NettyAvroRpcClient works with a host that has only an IP address associated with it but no hostname, some operations take too long (a few seconds vs expected millis). This affects most of exceptions throwing and a part of logging.
> This happens because of the unnecessary and expensive hostname lookup when converting NettyAvroRpcClient to String.
