James Clampffer updated HDFS-10441:
-----------------------------------
Attachment: HDFS-10441.HDFS-8707.011.patch
New patch ready to go (lots of manual testing, will file jira for adding CI
tests)
-Get rid of RpcEngine::ha_enabled_, switch "ha_persisted_info_ &&
ha_persisted_info->is_enabled()" into just a check on ha_persisted_info. The
only call left to is_enabled is to check if it is in a valid state, after that
a non-null pointer is sufficient to determine if it's HA.
-got rid of declatations for HANamenodeTracker::IsActiveNamenode
/IsStandbyNamenode
-fix the warning when we get more than two namenodes as part of a nameservice.
It would warn when we had two nodes.. ">" vs ">="
-turn the default max rpc retries to zero. This was hitting a signed to
unsigned conversion issue when using -1. This prevented the last patch from
properly failing over on timed out connections.
