HBaseSpanReceiver (htrace-hbase 4.2.0-incubating API)

java.lang.Object
- org.apache.htrace.core.SpanReceiver
- - org.apache.htrace.impl.HBaseSpanReceiver

All Implemented Interfaces:

Closeable, AutoCloseable
```
public class HBaseSpanReceiver
extends SpanReceiver
```
HBase is an open source distributed datastore. This span receiver store spans into HBase. HTrace spans are queued into a blocking queue. From there background worker threads will send them to a HBase database.

    Run basic test. Adds span to an existing htrace table in an existing hbase setup. Requires a running hbase to send the traces too with an already created trace table (Default table name is 'htrace' with column families 's' and 'i').
    
    Parameters:
    
    args - Default arguments which passed to main method
    
    Throws:
    
    InterruptedException - Thread.sleep() can cause interruption in current thread.
