[jira] [Created] (HADOOP-8068) HA: void methods can swallow
exceptions when going through failover path
HA: void methods can swallow exceptions when going through failover path
------------------------------------------------------------------------
Key: HADOOP-8068
URL: https://issues.apache.org/jira/browse/HADOOP-8068
Project: Hadoop Common
Issue Type: Bug
Components: ha, ipc
Affects Versions: HA Branch (HDFS-1623)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Blocker
While running through scale testing, we saw an issue where clients were getting LeaseExpiredExceptions. We eventually tracked it down to the fact that some {{create}} calls had timed out (having been sent to a NN just before it crashed) but the resulting exception was swallowed by the retry policy code paths.
