balance是啥，顾名思义 是个平衡器
主要是平衡各个datanode之间的使用
?网上的文档一个比一个写的6结果，有的命令都拼错了。。。而且你知道究竟平衡的是啥么
直接上官网
https://hadoop.apache.org/docs/r3.2.2/hadoop-project-dist/hadoop-hdfs/HDFSCommands.html#balancer--查看balance 也就是集群之间转移数据的速度
hdfs dfsadmin -getBalancerBandwidth node17:9867?
Balancer bandwidth is 10485760 bytes per second.? --10M嫌慢 设置20M
这里权限有点问题。。。认证hdfs
hdfs dfsadmin -setBalancerBandwidth 20971520
[root@worker01 /home/devuser]# hdfs dfsadmin -setBalancerBandwidth ?20971520
NumberFormatException: For input string: "?20971520"

--这里的时候我遇到一个问题 ip我知道，这个端口是啥。。但是我注意这个是ipc_port?
开始准备balancer
[root@worker01 /home/devuser]# hdfs balancer --help
Usage: hdfs balancer
[-policy <policy>] the balancing policy: datanode or blockpool
[-threshold <threshold>] Percentage of disk capacity
[-exclude [-f <hosts-file> | <comma-separated list of hosts>]] Excludes the specified datanodes.
[-include [-f <hosts-file> | <comma-separated list of hosts>]] Includes only the specified datanodes.
[-source [-f <hosts-file> | <comma-separated list of hosts>]] Pick only the specified datanodes as source nodes.
[-blockpools <comma-separated list of blockpool ids>] The balancer will only run on blockpools included in this list.
[-idleiterations <idleiterations>] Number of consecutive idle iterations (-1 for Infinite) before exit.
[-runDuringUpgrade] Whether to run the balancer during an ongoing HDFS upgrade.This is usually not desired since it will not affect used space on over-utilized machines.
Generic options supported are:
-conf <configuration file> specify an application configuration file
-D <property=value> define a value for a given property
-fs <file:///|hdfs://namenode:port> specify default filesystem URL to use, overrides 'fs.defaultFS' property from configurations.
-jt <local|resourcemanager:port> specify a ResourceManager
-files <file1,...> specify a comma-separated list of files to be copied to the map reduce cluster
-libjars <jar1,...> specify a comma-separated list of jar files to be included in the classpath
-archives <archive1,...> specify a comma-separated list of archives to be unarchived on the compute machines
The general command line syntax is:
command [genericOptions] [commandOptions]
?这时候要考虑一个问题？怎么样才算平衡？
比如10个dn，每个100G容量，共计1T， 总共使用了200G 其中 dn1使用了1k dn2使用了99G
那么我要怎么平衡？ dn1和dn2平衡到20G还是50G。我也不知道。
开始实验
threshold?
hdfs balancer -threshold 5? --阈值=5?也就是容忍datanode数据的差距是5%

结果很有意思的是打印日志的时候报错了。来分析下日志
1.Using a threshold of 5.0 说明获取到阈值
2.namenodes ?= [hdfs://s2cluster] 获取到集群信息 并且是HA
3.included nodes = [] ，excluded nodes = [] 说明我们没有设置指定哪些节点或者排除哪些节点
4.dfs.balancer.xx 打印了很多默认参数
5.?3 over-utilized: [9.134.117.90:1004:DISK, 9.134.124.14:1004:DISK, 9.134.116.73:1004:DISK]
5 underutilized: [9.134.80.60:1004:DISK, 9.134.81.221:1004:DISK, 9.134.124.36:1004:DISK, 9.134.81.127:1004:DISK, 9.134.80.64:1004:DISK]
这里说的是3个超过了限额的。5个低于限额的。我们来先看下这3个over发现其实有问题的。
?
发现其实这三个没有相似处。暂且不管。
6.开始分配over->under
7开始move结果报错了，Operation category READ is not supported in state standby 这个不用说肯定是用到了standby的节点?
8.关键日志, while invoking NamenodeProtocolTranslatorPB.getBlocks over master.data.com/9.134.64.234:8020. Trying to failover immediately. 这个b怎么就用的mater，下图可以看到master处于备用阶段，按照ha应该是可以用node01的。淦！
?9、但是后面的日志惊奇的发现他又开始用node01的active nn了。并且有开始move的日志了
10、Failed to move blk_1074919453_1178890 with size=134217728 from 9.134.68.200:1004:DISK to 9.134.81.127:1004:DISK through 9.134.80.60:1004
java.io.IOException: Got error, status=ERROR, status message Not able to receive block 1074919453 from /9.134.70.1:44227 because threads quota is exceeded., reportedBlock move is failed 好像是thread超过限额了？
-----------------------
上面的命令说明了啥？
只要你设置了阈值那么就会立马起作用！！！?
于是改变策略我只移动两个nn的。
?发现根本就没有低于阈值或者高于阈值的。。感觉这里有问题。
hdfs balancer -threshold 5 再次使用
之前取销是因为一直报错。。。后面发现这些报错不用管。等十几秒就会正常。前面都是连接错误啥的。
后面正常了就会显示 正在从a 移到b?
?这里显示完成了。但是我在cdh的控制页面发现还是一样的。
?其实我这里放了一个错误！！
磁盘的使用情况不是hdfs的容量的使用情况！！
磁盘的使用情况df -h以node17为例！cdh显示 376G/491G
?
?node17所有容量相加 差不多是500多G，但是/data目录是394G，使用的差不多是302+51=353G
?
hdfs dfs -report 搜索node17
?
?这里显示configured Capacity 是383G， dfs实际使用116G 非dfs使用175G?
一般来说hdfs目录是挂载在/data目录的。
可以看到dfs占用了117G 其余的非hdfs差不多是5.7+7.1+8.7+137+11+其余的=175G
此时我们可以得到如下结论
/data目录本身有394G内存 与这个report的383G差不多。（这个误差我不知道为啥。）
/data目录有比如kudu的tablet log啥的这些属于非hdfs的文件，占用了175G和report一样！！
/data/dfs =117G和我们report的116.08G一样！
这时才明白 我为什么我上面看到node17 node18差别那么大，怎么不能balance了把，
截图node18 /data目录容量。因为这上面他本身dfs占用内存也不少
而node17的tablet目录也有100多G 让我误以为两者相差很多
当前这个都是我balance后的截图。。balance前两者是否平衡，我也不能回到过去了。。
总结
我们平衡hdfs，是为了平衡什么呢？
/data目录？/data/dfs下的容量？/data/dfs的容量占/data的百分比？
个人认为是/data/dfs的容量占/data的百分比。
由于我之前已经balance成功了。
可以看到所有的dn节点DFS Used% 差不多都是25-35之间，刚好符合我们的比例+_5%
Configured Capacity: 10424513773568 (9.48 TB)
Present Capacity: 7435669957834 (6.76 TB)
DFS Remaining: 4419545119946 (4.02 TB)
DFS Used: 3016124837888 (2.74 TB)
DFS Used%: 40.56%
9.48T是所有机器的/data目录容量
Present Capacity 是什么？先留下疑问
2.74 T是所有机器的/data/dfs目录容量
40.56%是 2.74/6.72 那么平均的百分比应该是40呀我们的threhold=5那么其余的dn应该是35-45%呀
注意下面的dn 以node19为例
Name: 9.134.115.141:1004 (node19.data.com)
Configured Capacity: 411883184128 (383.60 GB)
DFS Used: 119300038656 (111.11 GB)
Non DFS Used: 51429728256 (47.90 GB)
DFS Remaining: 219661856768 (204.58 GB)
DFS Used%: 28.96%
DFS Remaining%: 53.33%
383.60 GB 是/data目录的
111.11 GB 是/data/dfs目录的
28.96% =111.11G/383G
这个怎么百分比会这么少呢？按道理来说，每天机器差不多都是25-35%，那么total也应该是30左右呀怎么会是40%
有意思的事情出来了。可以看到我们
每个dn的dfs used差不多是110-120G那么23个节点就是2.xT 等于我们上面的2.74T。
dn中容量为383G的有14台 482G的有9台，总容量=383*14+482*9=9.7T
所以这里存在一个问题！！！！
所有dn的 DFS Used%= DFS Used/Present Capacity
每个dn的?DFS Used%=DFS Used/Configured Capacity
所以这里是有出入的。
所以关键在present Capacity 个人猜测是?Configured Capacity -所有的Non DFS Used
所以Present Capacity=9.48T-2.25T= 7.23T貌似不对...我也没办法了。
虽然这个问题没解决。但是有了如下收获！！
1. 设置转移速度， 设置balance阈值
2.记住balance之前 hdfs dfsadmin -report 查看各个dn的dfs used%
3.这里balance的是 /data/dfs目录 占/data目录的百分比。
4.一般来说要么设置dfs.datanode.data.dir = /data 那么就不要把其余工作目录设置到data。
因为比如每个dn容量为500G，但是某个dn 的/data目录里有个400G的文件，那么这个dn的dfs used在用到20%的时候就会出现问题。这个时候可以通过df -h 来排查。当然你排查了也没用。因为这个400G的文件就是在这！！！
