程序连接不到HBase

Question

HBaseUtils程序运行异常，

下面是报错信息

在虚拟机中查看ZK日志，发现已经连接，但是之后会异常退出，可能的原因是连接时间长被中断

但是HBase日志中没有任何连接信息。意味着连接到zk并分配session之后，程序并没有连接HBase

ZK日志如下

2017-12-06 11:51:11,307 [myid:] - INFO  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@197] - Accepted socket connection from /192.168.43.233:52001

程序报错后，并没有结束。继续卡住，过一段时间后exit 0 结束。此时ZK的日志文件增加

2017-12-06 11:59:46,211 [myid:] - WARN  [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxn@354] - Exception causing close of session 0x16029dd9542000c due to java.io.IOException: Connection reset by peer

这段时间程序的状态是：先报错，但程序没有中断，最后过了一会，程序中断

去查看HBase日志文件，发现这段时间没有任何程序连接HBase

HBase配置文件如下

但是在HBase shell中可以创建表，可以put进数据。

每次使用API调用就会报如上错误，因为是初学者。。所以2天了没有解决。求老师帮忙

在windows下开发的话，你要连虚拟机的hbase去操作，你在idea里弄个hbase-site.xml试试，把hbase那些配置信息加上去

  这个问题我发现是出在zk返回给程序hbase的注册地址，127.0.0.1,然后程序就真在本地找hbase，最后就导致连接异常。但是不知道该怎么解决。修改了虚拟机中的hbase配置文件，hbase.site.xml将localhost改成ip地址也不行，它还会给程序返回127.0.0.1

你的hdfs的端口是9000还是8020？

• 提问者 十里桃花舞丶 #1

  我的端口是9000

• 提问者 十里桃花舞丶 #2

  hbase shell可以建表，也能put进去数据

• 提问者 十里桃花舞丶 #3

  老师，我发现问题是出在程序连接到zk之后，zk返回hbase的注册地址，返回的是127.0.0.1，然后程序就在本地找hbase,找不到就会连接超时异常。这个应该怎么解决呀？
