We has already found and fix many case for SSH and AM.joinCluster, however it
seems exist many other cases all the same.
I first give a suggestion just mentioned in another issue:
Don't assign user regions in SSH until master is initialized, just like doing
the following
{code}
process(){
...
if (isCarryingRoot() || isCarryingMeta()){...}
...
int waitedTimeForMasterInitialized = 0;
while (!server.isStopped() && !services.isInitialized()) {
try {
if (waitedTimeForMasterInitialized == 0) {
LOG.info("Master is not initialized, waiting...");
}
Thread.sleep(100);
waitedTimeForMasterInitialized += 100;
} catch (InterruptedException e) {
Thread.currentThread().interrupt();
throw new IOException("Interrupted", e);
}
}
if (waitedTimeForMasterInitialized > 0) {
LOG.info("Recovery time calculation: waiting on master to be initialized
took "
+ waitedTimeForMasterInitialized + "ms");
}
...
}
{code}
In some cases, above code will increase recovery time, if we could fix many
cases caused by SSH and AM.joinCluster, I think it is valuable.
Correct me if wrong, thanks.
