[part of hbase-1583] We wait on leases to expire before regionserver goes down.
Rather, just let client fail
-------------------------------------------------------------------------------------------------------------
Key: HBASE-1609
URL: https://issues.apache.org/jira/browse/HBASE-1609
Project: Hadoop HBase
Issue Type: Improvement
Reporter: stack
Fix For: 0.20.0
Addressing this issue will help hbase-1583. We should do for 0.20.0 and
perhaps for 0.19.x even.
Currently, if outstanding leases, in HRegion close, we'll hang until lease
expires. Could be a minute. Could be worse, the client might come in and
renew the lease a few times at least till it finishes out the region. This
gets in way of regionserver shutting down fast.
J-D suggests that regionserver should just go down and outstanding clients
should fail rather than try and be nice to outstanding clients (in his case,
his MR job had failed so no clients... but we insist on lease expiring).
