[jira] [Updated] (CASSANDRA-8808) CQLSSTableWriter: close does not
work + more than one table throws ex
[ https://issues.apache.org/jira/browse/CASSANDRA-8808?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Benjamin Lerer updated CASSANDRA-8808:
--------------------------------------
Attachment: CASSANDRA-8808-trunk.txt
CASSANDRA-8808-2.1.txt
CASSANDRA-8808-2.0.txt
The patch has been build on top of the one of [~carlyeks] for CASSANDRA-8251.
The patch use {{Config.isClientMode}} to prevent:
# {{DatabaseDescriptor}} to trigger unecessary threads
# calls to {{Keyspace}} which cause errors due to the uncomplete configuration
As {{CQLSSTableWriter}} must always be used on the client side, {{Config.setClientMode(true)}} is called in a static initialization in {{CQLSSTableWriter}}.
In trunk the client mode had been removed by mistake by CASSANDRA-7820. The patch for trunk re-introduce it.

> I have encountered the following two issues:
> - When closing the CQLSSTableWriter it just hangs the process and does nothing. (https://issues.apache.org/jira/browse/CASSANDRA-8281)
> - When writing more than one table throws ex. (https://issues.apache.org/jira/browse/CASSANDRA-8251)
> These issue can be reproduced with the following code:
> {code:title=test.java|borderStyle=solid}
> import org.apache.cassandra.config.Config;
> import org.apache.cassandra.io.sstable.CQLSSTableWriter;
> public static void main(String[] args) {
> Config.setClientMode(true);
> CQLSSTableWriter w1 = CQLSSTableWriter.builder()
> .inDirectory("/tmp/kspc/t1")
> .forTable("CREATE TABLE kspc.t1 ( id int, PRIMARY KEY (id));")
> .using("INSERT INTO kspc.t1 (id) VALUES ( ? );")
> .build();
> CQLSSTableWriter w2 = CQLSSTableWriter.builder()
> .inDirectory("/tmp/kspc/t2")
> .forTable("CREATE TABLE kspc.t2 ( id int, PRIMARY KEY (id));")
> .using("INSERT INTO kspc.t2 (id) VALUES ( ? );")
> .build();
> try {
> w1.addRow(1);
> w2.addRow(1);
> w1.close();
> w2.close();
> } catch (Exception e) {
> System.out.println(e);
> }
