： JAVA apiリモートhbaseエラーorg.apache.haadoop.hbase.client.RetriesExhaustedException:Failed after attempts=36,exceptions:Tue Jul 19 16:36:05 CST 2016,null,java.net.SocketTimeoutException:callTimeout=60000,callDuration=79721:row'testtable,'on table'on table'hbase:meta'at region=hbase:meta:meta、 hostname=ubuntu,16020,1468916750524, seqNum=0

： windows 10 idea下Java APIリモートhbase、hbaseは仮想環境下にインストールされ、NATネットワークモードを採用し、hbase IPアドレスは192.168.137.25である.Windows 10 vmnet 8 IPは192.168.137.1で双方ともping通が可能で、ネットワークの問題を排除します.

：まず位置決めエラーの原因:Caused by: java.net.UnknownHostException: ubuntu ubuntuホスト名を解析できません.ここでubuntuはhbaseが存在する仮想マシンのホスト名です.ubuntuホストに対応するIPアドレスが解析されず、(1)まずubuntuホスト下hosts情報gedit/etc/hosts 127.0.0.1 localhost 127.0.1.1 ubuntu

を表示する.
The following lines are desirable for IPv 6 capable hosts(ここでは#コメント、エディタの都合で手動文字コメントに変更):1 ip 6-localhost ip 6-loopback fe00::0 ip 6-localnet ff 00:0 ip 6-mcastprefix ff 02::1 ip 6-allnodes ff 02::2 ip 6-allrouters

(2)    java       ：

     config = HBaseConfiguration.create();
	 config.set("hbase.zookeeper.quorum", "192.168.137.25");
	 config.set("hbase.zookeeper.property.clientPort", "2181");  
	 config.set("hbase.master", "192.168.137.25:9001"); 

```(3)    ubuntu   IP   127.0.1.1 ，  192.168.137.25  ubuntu      127.0.1.1 ubuntu ```

127.0.0.1localhost（   #  ，       ，        ）
127.0.1.1  ubuntu（   #  ，       ，        ）

192.168.13725  ubuntu

```(4)     windows10       C:\Windows\System32\drivers\etc\hosts，  ```

```192.168.137.25 ubuntu ```(           )
