HBase でいくつかの問題が発生しています。hadoop を開始しようとすると、問題なく開始されます。しかし、HBase は動作しません。DataNode 、 HRegionServer 、secondaryNameNode などはすべて動作しますが、hbase を開始すると、HMaster は実行されません。「RegionServer はプロセスとして実行されています # xyz .まず停止してください。もう 1 つの奇妙な点は、HBase ログに「Matser started」と出力されていることですが、確認すると開始ではありません。問題を調査していますが、理解できません。手がかりが得られたら、ご案内します。以下のHBaseのログ
