>             Project: HBase
>          Issue Type: Improvement
>          Components: Client

> HTableMultiplexer class mentions following in the javadoc : "If any queue is full, the HTableMultiplexer starts to drop the Put requests for that particular queue."
> This could be improved by replacing following code in HTableMultiplexer.resubmitFailedPut() method :
> {code:title=HTableMultiplexer}
> try {
> 	succ = FlushWorker.this.getMultiplexer().put(tableName, failedPut, retryCount);
> } finally {
> 	FlushWorker.this.getRetryInQueue().decrementAndGet();
> 	if (!succ) {
> 		FlushWorker.this.getTotalFailedPutCount().incrementAndGet();
> 	}
> }
> {code}
> With : 
> {code}
> try {
> 	succ = FlushWorker.this.getMultiplexer().put(tableName, failedPut, retryCount);
> 	if (!succ) {
> 		if (!resubmitFailedPut(ps, oldLoc)) {
> 			FlushWorker.this.getTotalFailedPutCount().incrementAndGet();
> 		}
> 	}
> } finally {
> 	FlushWorker.this.getRetryInQueue().decrementAndGet();
> }
> {code}
