Subru Krishnan moved YARN-6213 to HADOOP-14105:

Key: HADOOP-14105 (was: YARN-6213)
Project: Hadoop Common (was: Hadoop YARN)
> Failure handling and retry for performFailover in RetryInvocationHandler
> -------------------------------------------------------------------------

> Key: HADOOP-14105
> URL: https://issues.apache.org/jira/browse/HADOOP-14105
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Botong Huang
> Assignee: Botong Huang
> Priority: Minor
>
> In {{RetryInvocationHandler}}, when the method invocation fails, we reply on
> {{FailoverProxyProvider}} to performFailover and get a new proxy, so that we
> can retry the method invocation.
> However, the performFailover and get new proxy itself might fail (throw
> exception or return null proxy). This is not handled properly currently, we
> end up throwing the exception out of the while loop. Instead, we should catch
> the exception (or check for null proxy) and retry performFailover again,
> until the max fail over count reaches the maximum.
