Jean-Daniel Cryans commented on HBASE-3767: ------------------------------------------- @Ted, I guess the improvement provided by setting the core pool size is minimal... I think I wouldn't even bother going all the way to using the number of CPUs and just start with 1. Cleaner code. > Cache the number of RS in HTable > -------------------------------- > > Key: HBASE-3767 > URL: https://issues.apache.org/jira/browse/HBASE-3767 > Project: HBase > Issue Type: Improvement > Affects Versions: 0.90.2 > Reporter: Jean-Daniel Cryans > Fix For: 0.90.3 > > > When creating a new HTable we have to query ZK to learn about the number of > region servers in the cluster. That is done for every single one of them, I > think instead we should do it once per JVM and then reuse that number for all > the others. -- This message is automatically generated by JIRA.
