Caleb Rackliffe commented on CASSANDRA-17740: --------------------------------------------- Hi [~yijunm_ts]. Do you mind creating a new Jira and assigning it to me? I can take a look at it, but the 4.0 mitigation might look a little different than the 4.1/trunk patch. > BulkLoader tool initializes schema unnecessarily via streaming > -------------------------------------------------------------- > > Key: CASSANDRA-17740 > URL: https://issues.apache.org/jira/browse/CASSANDRA-17740 > Project: Cassandra > Issue Type: Bug > Components: Tool/bulk load > Reporter: Caleb Rackliffe > Assignee: Caleb Rackliffe > Priority: Normal > Fix For: 4.1-beta1, 5.0 > > Time Spent: 2h 10m > Remaining Estimate: 0h > > Changes to streaming setup code for CASSANDRA-17663 mean that {{BulkLoader}} > initializes the schema/system keyspace, which is not what we want in a tool. > Initialization is due to a call to {{SystemKeyspace.getPreferredIP}} from the > {{BulkLoader}} when it starts to transmit the SSTables from the bulk loader > to the Cassandra instance. > {noformat} > getPreferredIP:1063, SystemKeyspace (org.apache.cassandra.db) > sendMessage:213, StreamingMultiplexedChannel > (org.apache.cassandra.streaming.async) > sendControlMessage:191, StreamingMultiplexedChannel > (org.apache.cassandra.streaming.async) > sendControlMessage:1033, StreamSession (org.apache.cassandra.streaming) > startStreamingFiles:1257, StreamSession (org.apache.cassandra.streaming) > prepareSynAck:802, StreamSession (org.apache.cassandra.streaming) > messageReceived:622, StreamSession (org.apache.cassandra.streaming) > run:76, StreamDeserializingTask (org.apache.cassandra.streaming) > run:30, FastThreadLocalRunnable (io.netty.util.concurrent) > run:748, Thread (java.lang) > {noformat} > The existing {{BulkLoaderTest}} fails to detect this as it doesn't actually > connect to anything so does not initialize streaming. > Affects 4.1 and trunk, and may affect 4.0, although the 4.0 patch for > CASSANDRA-17663 is different than 4.1+, and may require different mitigation. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
