-----------------------------
Summary: Making KafkaSytemAdmin's metadataConsumer accesses
thread-safe, enabling StreamRegexMonitors only when required
Key: SAMZA-2152
URL: https://issues.apache.org/jira/browse/SAMZA-2152
Project: Samza
Issue Type: Bug
Reporter: Rayman
StreamPartitionCountMOnitor and StreamRegexMonitor use the KafkaSystemAdmin,
which has a kafka-consumer. Kafka consumer is not thread-safe, therefore
explicit synchronization is required for metadata accesses. StreamRegexMonitor
is not to be enabled when there is no regex input.
