[jira] [Updated] (HBASE-4785) Improve recovery time of HBase client when a region server dies.
[ 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 (SoftValueK,V) to a newly created TreeSetEntryK,V. 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. And it incurs this *timeout* cost for every region being served by the dead region server. Remove this overhead by clearing the entries in cache that have the dead region server as their values. -- This message is automatically generated by JIRA.
