[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);
>   }
