| There can only be one <a href="../../../../../org/apache/hadoop/hbase/procedure/ZKProcedureMemberRpcs.html" title="class in org.apache.hadoop.hbase.procedure"><code>ZKProcedureMemberRpcs</code></a> per procedure type per member, |
| since each procedure type is bound to a single set of znodes. You can have multiple |
| <a href="../../../../../org/apache/hadoop/hbase/procedure/ZKProcedureMemberRpcs.html" title="class in org.apache.hadoop.hbase.procedure"><code>ZKProcedureMemberRpcs</code></a> on the same server, each serving a different member |
| name, but each individual rpcs is still bound to a single member name (and since they are |
| used to determine global progress, its important to not get this wrong). |
| <p> |
| To make this slightly more confusing, you can run multiple, concurrent procedures at the same |
| time (as long as they have different types), from the same controller, but the same node name |
| must be used for each procedure (though there is no conflict between the two procedure as long |
| as they have distinct names). |
| <p> |
| There is no real error recovery with this mechanism currently -- if any the coordinator fails, |
| its re-initialization will delete the znodes and require all in progress subprocedures to start |
| anew.</div> |
