the class ADTaskManager method initRealtimeTaskCacheAndCleanupStaleCache.

/**
 * Init realtime task cache and clean up realtime task cache on old coordinating node. Realtime AD
 * depends on job scheduler to choose node (job coordinating node) to run AD job. Nodes have primary
 * or replica shard of AD job index are candidate to run AD job. Job scheduler will build hash ring
 * on these candidate nodes and choose one to run AD job. If AD job index shard relocated, for example
 * new node added into cluster, then job scheduler will rebuild hash ring and may choose different
 * node to run AD job. So we need to init realtime task cache on new AD job coordinating node and
 * clean up cache on old coordinating node.
 *
 * If realtime task cache inited for the first time on this node, listener will return true; otherwise
 * listener will return false.
