Mike Drob commented on HBASE-20273: ----------------------------------- More notes, comparing what our default HBaseConfiguration gives between 1.2.x and 2.0.0-beta-2. If there were changes between 1.2 and 1.4, then some of these may be redundant. Likewise, if there were changes past beta-2, then they're missing from this list. The following properties are no longer present: * hbase.master.catalog.timeout * hbase.regionserver.catalog.timeout * hbase.metrics.exposeOperationTimes * hbase.metrics.showTableName * hbase.online.schema.update.enable * hbase.thrift.htablepool.size.max It appears that the following properties have changed defaults: * hbase.regions.slop (0.2 -> 0.001) * hbase.hstore.blockingStoreFiles (10 -> 16) * hbase.http.max.threads (10 -> 16) * hbase.client.max.perserver.tasks (5 -> 2) * hbase.normalizer.period (1800000 -> 300000) * hbase.regionserver.region.split.policy (IncreasingToUpperBoundRegionSplitPolicy -> SteppingSplitPolicy) The property hbase.hregion.percolumnfamilyflush.size.lower.bound has been renamed to hbase.hregion.percolumnfamilyflush.size.lower.bound.min > [DOC] include call out of additional changed config defaults in 2.0 upgrade > --------------------------------------------------------------------------- > > Key: HBASE-20273 > URL: https://issues.apache.org/jira/browse/HBASE-20273 > Project: HBase > Issue Type: Sub-task > Components: documentation > Affects Versions: 2.0.0 > Reporter: Sean Busbey > Priority: Major > > Copied from feedback on HBASE-19158 from [~mdrob]: > {quote} > Default settings/configuration properties changed/renamed: > HBASE-19919 > HBASE-19148 > HBASE-18307 > HBASE-17314 > HBASE-15784 > HBASE-15027 > HBASE-14906 > HBASE-14521 > {quote} > More detail later from [~mdrob]: > {quote} > would like to see notes that: > hbase.master.cleaner.interval changed from 1 min to 10 min > MasterProcedureConstants.MASTER_PROCEDURE_THREADS defaults to CPU/4 instead > of CPU > hbase.rpc.server.nativetransport renamed to hbase.netty.nativetransport > hbase.netty.rpc.server.worker.count renamed to base.netty.worker.count > hbase.hfile.compactions.discharger.interval renamed to > hbase.hfile.compaction.discharger.interval > hbase.hregion.percolumnfamilyflush.size.lower.bound removed at site level, > but can still be applied at table level > hbase.client.reties.number now counts the total number of retries, not the > total number of tries > {quote} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
