[ https://issues.apache.org/jira/browse/HBASE-4785?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Nicolas Spiegelberg updated HBASE-4785: --- Attachment: HBASE-4785.patch Fixes SoftValueSortedMap. Internal comments: Currently SoftValueSortedMap.entrySet() tries to iteraate through the entry set of the underlying map, and put all the values (SoftValue) to a newly created TreeSet>. The entry set of SortedMap is already sorted, so it's not necessary to have a TreeSet to sort those entries again upon adding. This gets rid of the runtime class cast exception because it does not require comparing anymore. > Improve recovery time of HBase client when a region server dies. > > > Key: HBASE-4785 > URL: https://issues.apache.org/jira/browse/HBASE-4785 > Project: HBase > Issue Type: Improvement >Reporter: Nicolas Spiegelberg >Assignee: Nicolas Spiegelberg >Priority: Minor > Fix For: 0.94.0 > > Attachments: HBASE-4785.patch, HBASE-4785.patch > > > When a region server dies, the HBase client waits until the RPC timesout > before learning that it needs to check META to find the new location of the > region.
