A concurrency issue on SoftValueSortedMap
-----------------------------------------
Key: HBASE-5088
URL: https://issues.apache.org/jira/browse/HBASE-5088
Project: HBase
Issue Type: Bug
Components: client
Affects Versions: 0.90.4, 0.94.0
Reporter: Jieshan Bean
SoftValueSortedMap is backed by a TreeMap. All the methods in this class are
synchronized. If we use this method to add/delete elements, it's ok.
But in HConnectionManager#getCachedLocation, it use heapMap to get a view from
SoftValueSortedMap#internalMap. Once we operate
on this view map(like add/delete) in other threads, a concurrency issue may
occur.
