Elliott Clark updated HBASE-16093: ---------------------------------- Assignee: Elliott Clark Status: Patch Available (was: Open) > Splits failed before creating daughter regions leave meta inconsistent > ---------------------------------------------------------------------- > > Key: HBASE-16093 > URL: https://issues.apache.org/jira/browse/HBASE-16093 > Project: HBase > Issue Type: Bug > Components: master, Region Assignment > Affects Versions: 1.2.1, 1.3.0 > Reporter: Elliott Clark > Assignee: Elliott Clark > Priority: Critical > Fix For: 1.3.0 > > Attachments: HBASE-16093.branch-1.patch > > > This is on branch-1 based code only. > Here's the sequence of events. > # A regionserver opens a new region. That regions looks like it should split. > # So the regionserver starts a split transaction. > # Split transaction starts execute > # Split transaction encounters an error in stepsBeforePONR > # Split transaction starts rollback > # Split transaction notifies master that it's rolling back using > HMasterRpcServices#reportRegionStateTransition > # AssignmentManager#onRegionTransition is called with SPLIT_REVERTED > # AssignmentManager#onRegionSplitReverted is called. > # That onlines the parent region and offlines the daughter regions. > However the daughter regions were never created in meta so all that gets done > is that state for those rows gets OFFLINE. Now all clients trying to get the > parent instead get the offline daughter. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
