3.2.1 查询集群状态信息（status命令）
status命令用于查看当前HBase集群的状态信息。
语法：
status 'simple' status 'summary' status 'detailed' status 'replication' status 'replication', 'source' status 'replication', 'sink'
范例一：查看集群最简洁的状态信息
hbase(main):001:0> status 'simple' active master: myhbase:16000 1631620932096 0 backup masters 1 live servers myhbase:16020 1631620936415 requestsPerSecond=0.0, numberOfOnlineRegions=4, usedHeapMB=55, maxHeapMB=1161, numberOfStores=4, numberOfStorefiles=4, storefileUncompressedSizeMB=0, storefileSizeMB=0, memstoreSizeMB=0, storefileIndexSizeMB=0, readRequestsCount=228, writeRequestsCount=14, rootIndexSizeKB=0, totalStaticIndexSizeKB=0, totalStaticBloomSizeKB=0, totalCompactingKVs=15, currentCompactedKVs=15, compactionProgressPct=1.0, coprocessors=[MultiRowMutationEndpoint] 0 dead servers Aggregate load: 0, regions: 4
范例二：查看集群详细的状态信息
