Question

当我尝试使用java hbase客户端在我的aws hbase上创建表时，它给了我例外：

org.apache.hadoop.hbase.client.RetriesExhaustedException: Failed after attempts=36, exceptions:

Sun Dec 13 08:26:29 EST 2015, null, java.net.SocketTimeoutException: callTimeout=60000, callDuration=69130: row 'wujintao,,00000000000000' on table 'hbase:meta' at region=hbase:meta,,1.1588230740, hostname=Slave1,60020,1449708947932, seqNum=0

我的java代码是这样的：

public static Configuration configuration; 
static { 
    configuration = HBaseConfiguration.create(); 
    configuration.set("hbase.zookeeper.property.clientPort", "2181"); 
    configuration.set("hbase.zookeeper.quorum","ec2-52-2-133-43.compute-1.amazonaws.com,ec2-52-70-140-152.compute-1.amazonaws.com,ec2-52-70-195-91.compute-1.amazonaws.com"); 
//  configuration.set("hbase.zookeeper.property.clientPort","2181"); 

    configuration.set("hbase.master", "*ec2-52-2-133-43.compute-1.amazonaws.com:9000"); 
}

是否意味着它已连接到主服务器但在从服务器上失败了？为什么失败？

Answer 1

是否可以从客户端计算机和主服务器访问/ etc / hosts文件或Slave1主机名中定义的First Formate:- --------------- NSString * mainStringvalue = [IdArray objectAtIndex:12]; NSDictionary *mainDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @"COLLECTION",@"key1", mainStringvalue,@"key2" , nil]; Second Formate:- ---------------- NSDictionary *mainDictionary = [NSDictionary dictionaryWithObjectsAndKeys: @"COLLECTION",@"key1", @"15",@"key2" , nil];？ Hbase和其他人使用主机名，即使您尝试使用ip连接，它也会返回主机名，并尝试在下次调用时使用它。

尝试使用java hbase客户端连接到aws ec2 Hbase
