------------------------------------
Summary: 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
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.
