Alex Liu commented on CASSANDRA-6091: ------------------------------------- If two token ranges have the same list of endpoints, they can be merged into a sudo token range. e.g. {code} Range A [start_a, end_a) has endpoints[node_1, node_5, node_8] Range B [start_b, end_c) has endpoints[node_1, node_5, node_8] can be merged to sudo token range Sudo_Range_A_B [[start_a, end_a), [start_b, end_b)] {code} We need modify CqlPagingRecordRead to support multiple token ranges split > Better Vnode support in hadoop/pig > ---------------------------------- > > Key: CASSANDRA-6091 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6091 > Project: Cassandra > Issue Type: Bug > Components: Hadoop > Reporter: Alex Liu > Assignee: Alex Liu > > CASSANDRA-6084 shows there are some issues during running hadoop/pig job if > vnodes are enable. Also the hadoop performance of vnode enabled nodes are > bad for there are so many splits. > The idea is to combine vnode splits into a big sudo splits so it work like > vnode is disable for hadoop/pig job -- This message was sent by Atlassian JIRA (v6.1#6144)
