James Taylor commented on PHOENIX-3994: --------------------------------------- It's an HBase optimization and it doesn't have anything to do with local indexes. When a batch of data table writes come in, a percentage of the index updates will land on the same RS. The optimization causes the RPC stack to be bypassed completely. > Index RPC priority still depends on the controller factory property in > hbase-site.xml > ------------------------------------------------------------------------------------- > > Key: PHOENIX-3994 > URL: https://issues.apache.org/jira/browse/PHOENIX-3994 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.11.0 > Reporter: Sergey Soldatov > Priority: Critical > Attachments: PHOENIX-3994.patch > > > During PHOENIX-3360 we tried to remove dependency on > hbase.rpc.controllerfactory.class property in hbase-site.xml since it cause > problems on the client side (if client is using server side configuration, > all client request may go using index priority). Committed solution is using > setting the controller factory programmatically for coprocessor environment > in Indexer class, but it comes that this solution doesn't work because the > environment configuration is not used for the coprocessor connection > creation. We need to provide a better solution since this issue may cause > accidental locks and failures that hard to identify and avoid. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
