Subject [jira] [Created] (HBASE-19126) [AMv2] RegionStates/RegionStateNode cleanup
Date Mon, 30 Oct 2017 22:18:00 GMT
Yi Liang created HBASE-19126:

             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
