Uneeded sleep time for tests in hbase.master.ServerManager#waitForRegionServers
-------------------------------------------------------------------------------
Key: HBASE-4603
URL: https://issues.apache.org/jira/browse/HBASE-4603
Project: HBase
Issue Type: Improvement
Components: test
Affects Versions: 0.92.0
Environment: all.
Reporter: nkeywal
Assignee: nkeywal
Priority: Minor
This functions waits for at least 2 times
hbase.master.wait.on.regionservers.interval, defaulted at 3 seconds, i.e. 6
seconds for every mini hbase cluster starts.
In the context of a mini cluster, it's not useful, as the regions servers are
created locally.
Changing this to a lower value such as 100ms gives 5.8 second per HBase cluser
start. It should lower the build time on the apache server by more than 8%.
Beeing more aggressive (removing all the wait time) could be possible as well.
To be studied later.
