Date Fri, 08 Jan 2010 13:00:54 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-6221?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Loughran updated HADOOP-6221:
-----------------------------------

    Summary: Make it possible to interrupt RPC Client operations  (was: RPC.WaitForProxy swallows
InterruptedException)

Retitling this to cover the entire underlying problem: you cannot interrupt a Client if the
far end isn't responding.

> RPC.waitForProxy swallows any attempts to interrupt it while waiting for a proxy; this
makes it hard to shutdown a service that you are starting; you have to wait for the timeouts.

> There are only 4-5 places in the code that use either of the two overloaded methods,
removing the catch and changing the signature should not be too painful, unless anyone is
using the method outside the hadoop codebase.
