------------------------------

    Attachment: HBASE-9241_2.patch

Patch addressing Stack's comment. 

Moved preMasterInitialization hook before logging(set status) as master initialized.

@Ram,
bq. Like stop the master from starting - something like that?
If hbase.coprocessor.abortonerror configuration set to true we are aborting otherwise just
logging error. Isn't if fine?
{code}
    if (env.getConfiguration().getBoolean("hbase.coprocessor.abortonerror",false)) {
      // server is configured to abort.
      abortServer(env, e);
    } else {
{code}

> This hook helps in following cases.
> 1) When we are creating indexed table then there is a chance that master can go down
after successful creation of user table but index table creation not yet started.
> This hook helps to find such cases and create missing index table.
> 2) if any case there are mismatches in colocation of user and index regions we can run
balancer.
