Summary: [MTTR] Study assigns to see if we can make them faster
still
Key: HBASE-7007
URL: https://issues.apache.org/jira/browse/HBASE-7007
Project: HBase
Issue Type: Improvement
Reporter: stack
Looking at a cluster start, I saw that it took about 25 minutes to assign and
open 17k regions. 8 minutes was bulk assigning via zk. 17 minutes was opening
the regions. "HBASE-6640 [0.89-fb] Allow multiple regions to be opened
simultaneously" in trunk would help but maybe we can do less work up in zk for
instance; e.g. if 3.4.5, we can do bulk ops in zk (or make a bulk assign znode
that has many regions instead of one)
