failed update partition of topic

[gaozhangmin]

Fixes #11682

Motivation

1、tryCreatePartitionsAsync would create znode under managed-ledgers/public/default/persistent/ after success invoke

2、there are chance, updatePartitionedTopic would failed, and managed-ledgers znode would stay unclean. If We tried update partition once again , We would fail, because of managed-ledgers znode exists

pulsar/pulsar-broker/src/main/java/org/apache/pulsar/broker/admin/impl/PersistentTopicsBase.java

Lines 473 to 485 in 80171a7

	if (numPartitions <= 0) {
	throw new RestException(Status.NOT_ACCEPTABLE, "Number of partitions should be more than 0");
	}
	try {
	tryCreatePartitionsAsync(numPartitions).get(DEFAULT_OPERATION_TIMEOUT_SEC, TimeUnit.SECONDS);
	updatePartitionedTopic(topicName, numPartitions).get(DEFAULT_OPERATION_TIMEOUT_SEC, TimeUnit.SECONDS);
	} catch (Exception e) {
	if (e.getCause() instanceof RestException) {
	throw (RestException) e.getCause();
	}
	log.error("[{}] Failed to update partitioned topic {}", clientAppId(), topicName, e);
	throw new RestException(e);
	}

Modifications

clean up managed-ledger znode after we failed update partition.
