-------------------------------------
Summary: Updates to meta table server columns may be eclipsed
Key: HBASE-13709
URL: https://issues.apache.org/jira/browse/HBASE-13709
Project: HBase
Issue Type: Bug
Reporter: Enis Soztutar
Assignee: Enis Soztutar
Fix For: 2.0.0, 1.0.2, 1.2.0, 1.1.1
HBASE-11536 fixes a case where on a very rare occasion, the meta updates may be
processed out of order. The fix is to use the RS's timestamp for the server
column in meta update, but that actually opens up a vulnerability for clock
skew (see the discussions in the jira).
For the region replicas case, we can reproduce a problem where the server name
field is eclipsed by the masters earlier update because the RS is lagging
behind. However, this is not specific to replicas, but occurs more frequently
with it.
One option that was discussed was to send the master's ts with open region RPC
and use it.
