[jira] [Updated] (CASSANDRA-8619) using CQLSSTableWriter gives
ConcurrentModificationException
[ https://issues.apache.org/jira/browse/CASSANDRA-8619?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Igor Berman updated CASSANDRA-8619:
-----------------------------------
Description:
Using CQLSSTableWriter gives ConcurrentModificationException
I'm trying to load many timeseries into cassandra 2.0.11-1
using java driver 'org.apache.cassandra:cassandra-all:2.0.11'
{noformat}
java.util.ConcurrentModificationException
at java.util.TreeMap$PrivateEntryIterator.nextEntry(TreeMap.java:1115)
at java.util.TreeMap$ValueIterator.next(TreeMap.java:1160)
at org.apache.cassandra.db.ColumnIndex$Builder.build(ColumnIndex.java:126)
at org.apache.cassandra.io.sstable.SSTableWriter.rawAppend(SSTableWriter.java:202)
at org.apache.cassandra.io.sstable.SSTableWriter.append(SSTableWriter.java:187)
at org.apache.cassandra.io.sstable.SSTableSimpleUnsortedWriter$DiskWriter.run(SSTableSimpleUnsortedWriter.java:215)
schema
CREATE TABLE test.sample (ts_id bigint, yr int, t timestamp, v double, tgs set<varchar>, PRIMARY KEY((ts_id,yr), t)) WITH CLUSTERING ORDER BY (t DESC) AND COMPRESSION = {'sstable_compression': 'LZ4Compressor'};
statement:
INSERT INTO test.sample(ts_id, yr, t, v) VALUES (?,?,?,?)
{noformat}
with .withBufferSizeInMB(128); it happens more than with
.withBufferSizeInMB(256);
code based on http://planetcassandra.org/blog/using-the-cassandra-bulk-loader-updated/
writer.addRow(tsId, year, new Date(time), value);
Any suggestions will be highly appreciated
