Subject How does HBase deal with master switch?
Date Thu, 06 Jun 2019 13:37:28 GMT
Hi,

Recently from the book, ZooKeeper: Distributed Process Coordination, I find
a paragraph mentions that, HBase once suffered by

1) RegionServer started full gc and timeout on ZooKeeper. Thus ZooKeeper
regarded it as failed.
2) ZooKeeper launched a new RegionServer, and the new one started to serve.
3) The old RegionServer finished gc and thought itself was still active and
serving.

in Chapter 5 section 5.3.

I'm interested on it and would like to know how HBase community overcame
this issue.

Best,
tison.
