Cassandra: Get metadata using keyspace and table name - triggers

Question

I'm creating a custom trigger for casssandra.
So, to get the metadata, the statement in the given example trigger file fails.
TableMetadata metadata = Schema.instance.getTableMetadata(auditKeyspace, auditTable);
I get this error while build
AuditTrigger.java:27: error: package org.apaceh.cassandra.schema does not exist
[javac] import org.apaceh.cassandra.schema.TableMetadata;
[javac] ^
[javac] /home/bkoganti/cassandra/examples/triggers/src/org/apache/cassandra/triggers/AuditTrigger.java:28: error: cannot find symbol
[javac] import org.apache.cassandra.schema.Schema;
[javac] ^
[javac] symbol: class Schema
[javac] location: package org.apache.cassandra.schema
[javac] /home/bkoganti/cassandra/examples/triggers/src/org/apache/cassandra/triggers/AuditTrigger.java:50: error: cannot find symbol
[javac] TableMetadata metadata = Schema.instance.getTableMetadata(auditKeyspace, auditTable);
[javac] ^
[javac] symbol: class TableMetadata
[javac] location: class AuditTrigger
[javac] /home/bkoganti/cassandra/examples/triggers/src/org/apache/cassandra/triggers/AuditTrigger.java:50: error: package Schema does not exist
[javac] TableMetadata metadata = Schema.instance.getTableMetadata(auditKeyspace, auditTable);
[javac] ^
[javac] 4 errors
There is no class TableMetadata and Schema available.
So, how do I get the metadata using the keyspace name and table name.

This is a typo missed during some refactors. I created a jira and provided patch with fix here CASSANDRA-13796 you can see the change on github
audit.row()
.add("keyspace_name", update.metadata().keyspace)
- .add("table_name", update.metadata().table)
+ .add("table_name", update.metadata().name)
.add("primary_key", update.metadata().partitionKeyType.getString(update.partitionKey().getKey()));
