Pierre Chalamet created CASSANDRA-5121: ------------------------------------------
Summary: system.peers.tokens is empty after node restart Key: CASSANDRA-5121 URL: https://issues.apache.org/jira/browse/CASSANDRA-5121 Project: Cassandra Issue Type: Bug Components: Core Affects Versions: 1.2.0 Environment: Windows 8 / Java 1.6.0_37-b06 Reporter: Pierre Chalamet Priority: Minor Using a 2 nodes fresh cluster (127.0.0.1 & 127.0.0.2) running latest 1.2, I’m querying system.peers to get the nodes of the cluster and their respective token. But it seems there is a problem after either node restart. When both node starts up, querying system.peers seems ok: {code} 127.0.0.1> select * from system.peers; +-----------------+------------------------------------------+---------------+-----------+---------------------+-----------------+------------------------------------------+-------------------------------------------+ | data_center | host_id | peer | rack | release_version | rpc_address | schema_version | tokens | +=================+==========================================+===============+===========+=====================+=================+==========================================+===========================================+ | datacenter1 | 4819cbb0-9741-4fe0-8d7d-95941b0247bf | 127.0.0.2 | rack1 | 1.2.0 | 127.0.0.2 | 59adb24e-f3cd-3e02-97f0-5b395827453f | 56713727820156410577229101238628035242 | +-----------------+------------------------------------------+---------------+-----------+---------------------+-----------------+------------------------------------------+-------------------------------------------+ {code} But as soon as one node is restarted (let’s say 127.0.0.2), tokens column is then empty: {code} 127.0.0.1> select * from system.peers; +-----------------+------------------------------------------+---------------+-----------+---------------------+-----------------+------------------------------------------+-------------+ | data_center | host_id | peer | rack | release_version | rpc_address | schema_version | tokens | +=================+==========================================+===============+===========+=====================+=================+==========================================+=============+ | datacenter1 | 4819cbb0-9741-4fe0-8d7d-95941b0247bf | 127.0.0.2 | rack1 | 1.2.0 | 127.0.0.2 | 59adb24e-f3cd-3e02-97f0-5b395827453f | | +-----------------+------------------------------------------+---------------+-----------+---------------------+-----------------+------------------------------------------+-------------+ {code} {code} Log server side: DEBUG 22:08:01,608 Responding: ROWS [peer(system, peers), org.apache.cassandra.db.marshal.InetAddressType][data_center(system, peers), org.apache.cassandra.db.marshal.UTF8Type][host_id(system, peers), org.apache.cassandra.db.marshal.UUIDType][rack(system, peers), org.apache.cassandra.db.marshal.UTF8Type][release_version(system, peers), org.apache.cassandra.db.marshal.UTF8Type][rpc_address(system, peers), org.apache.cassandra.db.marshal.InetAddressType][schema_version(system, peers), org.apache.cassandra.db.marshal.UUIDType][tokens(system, peers), org.apache.cassandra.db.marshal.SetType(org.apache.cassandra.db.marshal.UTF8Type)] | 127.0.0.2 | datacenter1 | 4819cbb0-9741-4fe0-8d7d-95941b0247bf | rack1 | 1.2.0 | 127.0.0.2 | 59adb24e-f3cd-3e02-97f0-5b395827453f | null {code} Restarting the other node (127.0.0.1) restore back the tokens column. -- This message is automatically generated by JIRA.
