--------------------------------
Summary: [AMv2] RegionStates/RegionStateNode cleanup
Key: HBASE-19126
URL: https://issues.apache.org/jira/browse/HBASE-19126
Project: HBase
Issue Type: Improvement
Reporter: Yi Liang
Fix For: 2.0.0-beta-1
// Mutable/Immutable? Changes have to be synchronized or not?
// Data members are volatile which seems to say multi-threaded access is fine.
// In the below we do check and set but the check state could change before
// we do the set because no synchronization....which seems dodgy. Clear up
// understanding here... how many threads accessing? Do locks make it so one
// thread at a time working on a single Region's RegionStateNode? Lets presume
// so for now. Odd is that elsewhere in this RegionStates, we synchronize on
// the RegionStateNode instance
Open this jira to track some cleanups for RegionStates/RegionStateNode
