Jonathan Ellis resolved CASSANDRA-995. -------------------------------------- Resolution: Not A Problem If this is just saying that "I can't replay a commitlog written before -44, after applying 44 and restarting," then that is expected. Use nodetool drain before upgrading (or simply r/m the commitlog as you say). > restarting node crashes with NPE when, while replaying the commitlog, the > cfMetaData is requested > ------------------------------------------------------------------------------------------------- > > Key: CASSANDRA-995 > URL: https://issues.apache.org/jira/browse/CASSANDRA-995 > Project: Cassandra > Issue Type: Bug > Affects Versions: 0.7 > Environment: SVN rev 935070 > Reporter: Ted Zlatanov > > Removing the commitlog directory completely fixes this. I can reliably > reproduce it by 1) starting and configuring a schema with one keyspace, one > super CF with LongType supercolumns; 2) inserting data; 3) shutting down and > restarting the node. > Here's my schema expressed in cassidy.pl, should be obvious what the > parameters are: > ./cassidy.pl -server X -port Y -keyspace system 'kdefine test > org.apache.cassandra.locator.RackUnawareStrategy 2 > org.apache.cassandra.locator.EndPointSnitch' > ./cassidy.pl -server X -port Y -keyspace test 'fdefine Status Super LongType > BytesType comment=statuschanges,row_cache_size=0,key_cache_size=20000' > The problem seems to be related to CASSANDRA-44 as it happens when the CF > metadata is requested but I don't know what's causing it. > 10/04/16 15:25:11 INFO commitlog.CommitLog: Replaying > /home/cassandra/commitlog/CommitLog-1271449410100.log, > /home/cassandra/commitlog/CommitLog-1271449378151.log, > /home/cassandra/commitlog/CommitLog-1271449415800.log > java.lang.reflect.InvocationTargetException > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) > at java.lang.reflect.Method.invoke(Method.java:597) > at > org.apache.commons.daemon.support.DaemonLoader.load(DaemonLoader.java:160) > Caused by: java.lang.NullPointerException > at org.apache.cassandra.db.Table.<init>(Table.java:261) > at org.apache.cassandra.db.Table.open(Table.java:102) > at > org.apache.cassandra.db.commitlog.CommitLog.recover(CommitLog.java:233) > at > org.apache.cassandra.db.commitlog.CommitLog.recover(CommitLog.java:172) > at > org.apache.cassandra.thrift.CassandraDaemon.setup(CassandraDaemon.java:104) > at > org.apache.cassandra.thrift.CassandraDaemon.init(CassandraDaemon.java:151) > ... 5 more -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
