--------------------------------
Seems that HBASE-1291 is on the same subject, and it says:
bq. We currently use 10 seconds for zookeeper.session.timeout. I tried bumping
this down recently to 2 seconds, and it broke the tests. We need to investigate
why this change breaks our test.
So the timeout have been increased somewhere...
> 25s sleep when expiring sessions in tests

> Key: HBASE-4519
> URL: https://issues.apache.org/jira/browse/HBASE-4519
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.90.4
> Reporter: Jean-Daniel Cryans
> Fix For: 0.92.0
>
>
> There's a hardcoded 25 seconds sleep in HBaseTestingUtility.expireSession:
> {code}
> int sessionTimeout = 5 * 1000; // 5 seconds
> ...
> final long sleep = sessionTimeout * 5L;
> LOG.info("ZK Closed Session 0x" + Long.toHexString(sessionID) +
> "; sleeping=" + sleep);
> Thread.sleep(sleep);
> {code}
> I'm pretty sure this can be lowered at lot, and it would speed up a couple of
> tests. The only thing I'm afraid of is if this was made to accomodate flaky
> tests.
