------------------------------------------------
[~ifesdjeen], can you double check the changes.txt entry (I think it should be
3.11.1 instead of 3.11.0) and set fix version?
> CQLSSTableWriter unable to use blob conversion functions

> Key: CASSANDRA-12606
> URL: https://issues.apache.org/jira/browse/CASSANDRA-12606
> Project: Cassandra
> Issue Type: Bug
> Components: CQL, Tools
> Reporter: Mark Reddy
> Assignee: Alex Petrov
> Priority: Minor
> Fix For: 4.0, 3.0.x, 3.11.x
>
>
> Attempting to use blob conversion functions e.g. textAsBlob, from 3.0 - 3.7
> results in:
> {noformat}
> Exception in thread "main"
> org.apache.cassandra.exceptions.InvalidRequestException: Unknown function
> textasblob called

> at
> org.apache.cassandra.io.sstable.CQLSSTableWriter$Builder.build(CQLSSTableWriter.java:510)
> {noformat}
> The following snippet will reproduce the issue
> {code}
> String table = String.format("%s.%s", "test_ks", "test_table");
> String schema = String.format("CREATE TABLE %s (test_text text, test_blob
> blob, PRIMARY KEY(test_text));", table);
> String insertStatement = String.format("INSERT INTO %s (test_text, test_blob)
> VALUES (?, textAsBlob(?))", table);
> File tempDir = Files.createTempDirectory("tempDir").toFile();
> CQLSSTableWriter sstableWriter = CQLSSTableWriter.builder()
> .forTable(schema)
> .using(insertStatement)
> .inDirectory(tempDir)
> .build();
> {code}
> This is caused in FunctionResolver.get(...) when
> candidates.addAll(Schema.instance.getFunctions(name.asNativeFunction())); is
> called, as there is no system keyspace initialised.
