### What problem does this PR solve? 1. Issue Number: close #55426 When `max_meta_object_cache_num = 0`, the desc command fails because it tries to access disabled meta cache. ``` ERROR 1105 (HY000): errCode = 2, detailMessage = Unknown table '7311664922056505694' ``` So force set `max_meta_object_cache_num` > 0 2. Remove the removalListener of ExternalDatabase's meta cache, it may cause thread pool exausted: ``` "CommonRefreshExecutor-55" #19386 daemon prio=5 os_prio=0 tid=0x00007ef928005000 nid=0x61aa waiting on condition [0x00007ef8aaf5a000] java.lang.Thread.State: TIMED_WAITING (parking) at sun.misc.Unsafe.park(Native Method) - parking to wait for <0x00007f03c435af50> (a java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject) at java.util.concurrent.locks.LockSupport.parkNanos(LockSupport.java:215) at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.awaitNanos(AbstractQueuedSynchronizer.java:2078) at java.util.concurrent.LinkedBlockingQueue.offer(LinkedBlockingQueue.java:385) at org.apache.doris.common.ThreadPoolManager$BlockedPolicy.rejectedExecution(ThreadPoolManager.java:347) at java.util.concurrent.ThreadPoolExecutor.reject(ThreadPoolExecutor.java:830) at java.util.concurrent.ThreadPoolExecutor.execute(ThreadPoolExecutor.java:1379) at com.github.benmanes.caffeine.cache.BoundedLocalCache.notifyRemoval(BoundedLocalCache.java:333) at com.github.benmanes.caffeine.cache.BoundedLocalCache.removeNode(BoundedLocalCache.java:1882) at com.github.benmanes.caffeine.cache.BoundedLocalCache.clear(BoundedLocalCache.java:1819) at com.github.benmanes.caffeine.cache.LocalManualCache.invalidateAll(LocalManualCache.java:150) at org.apache.doris.datasource.metacache.MetaCache.invalidateAll(MetaCache.java:121) at org.apache.doris.datasource.ExternalDatabase.setUnInitialized(ExternalDatabase.java:123) at org.apache.doris.datasource.ExternalCatalog.lambda$null$2(ExternalCatalog.java:248) at org.apache.doris.datasource.ExternalCatalog$$Lambda$3280/1787323570.accept(Unknown Source) at java.util.Optional.ifPresent(Optional.java:159) at org.apache.doris.datasource.ExternalCatalog.lambda$makeSureInitialized$3(ExternalCatalog.java:248) at org.apache.doris.datasource.ExternalCatalog$$Lambda$2317/2029647164.onRemoval(Unknown Source) at com.github.benmanes.caffeine.cache.BoundedLocalCache.lambda$notifyRemoval$1(BoundedLocalCache.java:327) at com.github.benmanes.caffeine.cache.BoundedLocalCache$$Lambda$3279/2010922194.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:750) ```
