Question

我正在使用非托管zookeeper构建一个完全分布式的hbase集群。我几乎使用了这个例子并在其上面安装了hbase：https://github.com/kiwenlau/hadoop-cluster-docker

Hadoop和hdfs工作正常，但我用hbase：

得到了这个例外

2016-09-05 06:27:12,268 INFO  [hadoop-master:16000.activeMasterManager] zookeeper.MetaTableLocator: Failed verification of hbase:meta,,1 at address=hadoop-slave2,16020,1473052276351, exception=org.apache.hadoop.hbase.NotServingRegionException: Region hbase:meta,,1 is not online on hadoop-slave2.hadoopnet,16020,1473056813966
at org.apache.hadoop.hbase.regionserver.HRegionServer.getRegionByEncodedName(HRegionServer.java:2910)

这很闷，因为我在hbase shell上输入的任何命令都会返回以下错误：

ERROR: org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

使用--net = hadoopnet运行容器这是一个网络创建如下：

docker network create --driver=bridge hadoopnet

hbase webui显示了这个：

Region Servers
ServerName  Start time  Version Requests Per Second Num. Regions
hadoop-slave1,16020,1473056814064   Mon Sep 05 06:26:54 UTC 2016    1.2.2   0   0
hadoop-slave1.hadoopnet,16020,1473056814064 Mon Sep 05 06:26:54 UTC 2016    Unknown 0   0
hadoop-slave2,16020,1473056813966   Mon Sep 05 06:26:53 UTC 2016    1.2.2   0   0
hadoop-slave2.hadoopnet,16020,1473056813966 Mon Sep 05 06:26:53 UTC 2016    Unknown 0   0
Total:4     2 nodes with inconsistent version   0   0

我应该只有2个区域服务器，但是2个奇怪的hadoop-slave1.hadoopnet和hadoop-slave2.hadoopnet被添加到列表中。当我使用：

查看zk时

/usr/local/hbase/bin/hbase zkcli -server zk:2181 ls /hbase/rs

我只看到我的2区域服务器：hadoop-slave1,16020,1473056814064和hadoop-slave2,16020,1473056813966

看看zookeeper.MetaTableLocator：验证失败错误我看到hadoop-slave2,16020,1473052276351和hadoop-slave2.hadoopnet，16020,1473056813966混淆了。

这是我在所有服务器上的配置

Answer 1

我遇到同样的问题，如下所示：

hadoop 2.7.2
hbase 1.2.2
zookeeper 3.4.8

我注意到，hbase-1.2.2将hadoop的jar包含为2.5.1，将zookeeper＆jar的jar包括为3.4.6，我将它们升级为版本i＆＃39; m使用（hadoop＆amp; zookeeper），错误已经消失，但仍然发现[hostname].[docker-network]为区域服务器，除此之外，一切都很好。

由于主机名alisas，在docker NotServingRegionException上的HBase
