-----------------------------------
Summary: Make IntegrationTestReplication's waitForReplication()
smarter
Key: HBASE-15930
URL: https://issues.apache.org/jira/browse/HBASE-15930
Project: HBase
Issue Type: Improvement
Components: integration tests
Reporter: Dima Spivak
Assignee: Dima Spivak
{{IntegrationTestReplication}} is a great test, but can improved by changing
how we handle waiting between generation of the linked list on the source
cluster and verifying the linked list on the destination cluster. [Even the
code suggests this should be
done|https://github.com/apache/hbase/blob/master/hbase-it/src/test/java/org/apache/hadoop/hbase/test/IntegrationTestReplication.java#L251-252],
so I'd like to take it on. [~mbertozzi] and [~busbey] have both suggested a
simple solution wherein we write a row into each region on the source cluster
after the linked list generation and then assume replication has gone through
once these rows are detected on the destination cluster.
Since you lads at Facebook are some of the heaviest users, [~eclark], would you
prefer I maintain the API and add a new command line option (say {{\-c |
\-\-check-replication}}) that would run before any {{--generateVerifyGap}}
sleep is carried out as it is now?
