Stu Hood reassigned CASSANDRA-1434: ----------------------------------- Assignee: Jonathan Ellis (was: Stu Hood) * ColumnFamilyOutputFormat.createAuthenticatedClient calls socket.open, so the second open in RangeClient is getting {{TTransportException: Socket already connected}} * Logging a NPE for the first batch is pretty ugly * The default batchSize was increased back up to Long.MAX_VALUE: it should probably be significantly lower (32~128) for the reasons you've mentioned > ColumnFamilyOutputFormat performs blocking writes for large batches > ------------------------------------------------------------------- > > Key: CASSANDRA-1434 > URL: https://issues.apache.org/jira/browse/CASSANDRA-1434 > Project: Cassandra > Issue Type: Bug > Components: Hadoop > Reporter: Stu Hood > Assignee: Jonathan Ellis > Fix For: 0.7 beta 2 > > Attachments: > 0001-Switch-away-from-Multimap-and-fix-regression-introdu.patch, > 0002-Improve-concurrency-and-add-basic-retries-by-attempt.patch, > 0003-Switch-RingCache-back-to-multimap.patch, > 0004-Replace-Executor-with-map-of-threads.patch, 1434-v3.txt, 1434-v4.txt, > 1434-v5.txt > > > By default, ColumnFamilyOutputFormat batches > {{mapreduce.output.columnfamilyoutputformat.batch.threshold}} or > {{Long.MAX_VALUE}} mutations, and then performs a blocking write. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
