Michal Lefler created CASSANDRA-12575: -----------------------------------------
Summary: A Cassandra node gets corrupted and contains only "key" and "column1" columns Key: CASSANDRA-12575 URL: https://issues.apache.org/jira/browse/CASSANDRA-12575 Project: Cassandra Issue Type: Bug Environment: We use a 3 data center environment, each data center contains two Cassandra nodes. Reporter: Michal Lefler Attachments: 122310b.jpg, Site2_Tables.JPG, system.log, system.log.1.zip We executed our application for a few hours, and all the nodes were functioning correctly. Then, after a few hours, we suddenly started getting the following exceptions: com.datastax.driver.core.exceptions.InvalidQueryException: Undefined name siteId in where clause ('siteId = 'Site2-sdclab008-11-12'') [main_24] [TopologyManager.<init>()] com.datastax.driver.core.exceptions.InvalidQueryException: Undefined name siteId in where clause ('siteId = 'Site2-sdclab008-11-12'') at com.datastax.driver.core.exceptions.InvalidQueryException.copy(InvalidQueryException.java:50) at com.datastax.driver.core.DriverThrowables.propagateCause(DriverThrowables.java:37) at com.datastax.driver.core.DefaultResultSetFuture.getUninterruptibly(DefaultResultSetFuture.java:245) at com.datastax.driver.core.AbstractSession.execute(AbstractSession.java:64) at com.datastax.driver.core.AbstractSession.execute(AbstractSession.java:39) at com.traffix.openblox.core.utils.clustering.infrastructure.topology.TopologyDao.getEmsServers(TopologyDao.java:94) After some investigation, we found out that we got this kind of an exception whenever we tried to query EACH ONE OF THE TABLES of one of our Cassandra nodes. When we tried to query the tables directly using CQL, we got the following result: All the tables only had one column named "key" for the partition key, and a "columnx" column for each one of the clustering keys (column1, column2 etc.) For example: This query was executed on a healthy node: (siteId is the partition key, and flowType is the clustering key) cqlsh> SELECT * from statusflow.flow ; siteId | flowType | currentVersion | flowName | flowOwner | flowState | lockUpdatedTime | previousVersion | rev -----------------+-----------+----------------+-------------------+---------------+-----------+------------------+-----------------+----- EMS-roger-01-02 | statusApi | 5.1-787 | installation | | idle | 1472618536062180 | 5.1-787 | 1 EMS-roger-01-02 | topology | null | topology_inserted | 10.240.32.130 | idle | 1472618335876404 | null | 1 The same query was executed on the problematic node: cqlsh> SELECT * from statusflow.flow ; key | column1 -----------------+----------- EMS-roger-01-02 | statusApi EMS-roger-01-02 | topology We tried to restart the node, and also to performed a full repair, but nothing helped. Finally we had to delete the node's data entirely, and resync it from the other nodes. We saw these lines on the Cassandra log (may or may not be related to the problem): ERROR [main] 2016-08-28 14:20:01.272 CassandraDaemon.java:651 - Exception encountered during startup java.lang.AssertionError: org.apache.cassandra.exceptions.InvalidRequestException: unconfigured table roles at org.apache.cassandra.auth.CassandraRoleManager.prepare(CassandraRoleManager.java:458) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.auth.CassandraRoleManager.setup(CassandraRoleManager.java:144) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.service.StorageService.doAuthSetup(StorageService.java:1023) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.service.StorageService.joinTokenRing(StorageService.java:971) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.service.StorageService.initServer(StorageService.java:705) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.service.StorageService.initServer(StorageService.java:581) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.service.CassandraDaemon.setup(CassandraDaemon.java:315) [apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.service.CassandraDaemon.activate(CassandraDaemon.java:529) [apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.service.CassandraDaemon.main(CassandraDaemon.java:638) [apache-cassandra-2.2.4.jar:2.2.4] Caused by: org.apache.cassandra.exceptions.InvalidRequestException: unconfigured table roles at org.apache.cassandra.thrift.ThriftValidation.validateColumnFamily(ThriftValidation.java:116) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.cql3.statements.SelectStatement$RawStatement.prepare(SelectStatement.java:798) ~[apache-cassandra-2.2.4.jar:2.2.4] at org.apache.cassandra.auth.CassandraRoleManager.prepare(CassandraRoleManager.java:454) ~[apache-cassandra-2.2.4.jar:2.2.4] ... 8 common frames omitted -- This message was sent by Atlassian JIRA (v6.3.4#6332)
