Lars Hofhansl commented on HBASE-5986: -------------------------------------- +1 for 0.94, can't speak for 0.92. > Clients can see holes in the META table when regions are being split > -------------------------------------------------------------------- > > Key: HBASE-5986 > URL: https://issues.apache.org/jira/browse/HBASE-5986 > Project: HBase > Issue Type: Bug > Affects Versions: 0.92.1, 0.96.0, 0.94.1 > Reporter: Enis Soztutar > Assignee: Enis Soztutar > Fix For: 0.96.0 > > Attachments: 5986-v2.txt, HBASE-5986-test_v1.patch, > HBASE-5986_v3.patch > > > We found this issue when running large scale ingestion tests for HBASE-5754. > The problem is that the .META. table updates are not atomic while splitting a > region. In SplitTransaction, there is a time lap between the marking the > parent offline, and adding of daughters to the META table. This can result in > clients using MetaScanner, of HTable.getStartEndKeys (used by the > TableInputFormat) missing regions which are made just offline, but the > daughters are not added yet. > This is also related to HBASE-4335. -- This message is automatically generated by JIRA.
