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

    hbase(main):001:0> status 'detailed'
version 1.3.2
0 regionsInTransition
active master:  myhbase:16000 1631620932096
0 backup masters
