| <a href="../../../../../org/apache/hadoop/hbase/regionserver/HRegionServer.html" title="class in org.apache.hadoop.hbase.regionserver"><code>HRegionServer</code></a> process. |
| |
| Since most implementations will be interested in only a subset of hooks, this class uses |
| 'default' functions to avoid having to add unnecessary overrides. When the functions are |
| non-empty, it's simply to satisfy the compiler by returning value of expected (non-void) type. |
| It is done in a way that these default definitions act as no-op. So our suggestion to |
| implementation would be to not call these 'default' methods from overrides. |
| <br><br> |
| |
| <h3>Exception Handling</h3> |
| For all functions, exception handling is done as follows: |
| <ul> |
| <li>Exceptions of type <a href="https://docs.oracle.com/javase/8/docs/api/java/io/IOException.html?is-external=true" title="class or interface in java.io"><code>IOException</code></a> are reported back to client.</li> |
| <li>For any other kind of exception: |
| <ul> |
| <li>If the configuration <a href="../../../../../org/apache/hadoop/hbase/coprocessor/CoprocessorHost.html#ABORT_ON_ERROR_KEY"><code>CoprocessorHost.ABORT_ON_ERROR_KEY</code></a> is set to true, then |
| the server aborts.</li> |
| <li>Otherwise, coprocessor is removed from the server and |
| <a href="../../../../../org/apache/hadoop/hbase/DoNotRetryIOException.html" title="class in org.apache.hadoop.hbase"><code>DoNotRetryIOException</code></a> is returned to the client.</li> |
