优化

CDH6是一个分布式系统，它需要根据负载模式和硬件配置进行参数优化。以下是一些CDH6集群参数优化的建议：

HDFS 参数优化：

dfs.replication：该参数控制了数据块在集群中的副本数量。在大型集群中，建议将此值设置为3或更高，以确保数据的冗余备份。
dfs.namenode.handler.count：该参数控制处理NameNode请求的线程数。在大型集群中，建议将此值增加到10或更高，以提高响应速度。
dfs.datanode.max.transfer.threads：该参数控制DataNode之间传输数据的线程数，对于大流量的集群，可以适当增加此值。

YARN 参数优化：

yarn.scheduler.minimum-allocation-mb：该参数控制YARN调度器分配给每个容器的最小内存大小。根据任务的内存需求，可以适当调整此值。
yarn.nodemanager.resource.memory-mb：该参数控制每个NodeManager可用的总内存大小。在大型集群中，建议将此值设置为机器物理内存的70%到80%。
yarn.nodemanager.local-dirs：该参数控制NodeManager使用的本地磁盘路径，建议将其设置为多个磁盘的路径，以提高数据读写的效率。

HBase 参数优化：

hbase.regionserver.handler.count：该参数控制处理RegionServer请求的线程数。在大型集群中，建议将此值增加到20或更高，以提高响应速度。
hbase.regionserver.wal.codec：该参数控制WAL使用的编解码方式。如果您的集群有高写入负载，可以考虑使用snappy压缩来减少磁盘空间的占用。
hbase.hregion.memstore.block.multiplier：该参数控制MemStore块的大小，这对读写性能有影响。建议根据您的负载模式和硬件配置进行调整。

以上是CDH6集群参数优化的建议，但实际上，参数优化需要结合特定的场景和硬件情况来进行。因此在进行调整之前，建议先备份配置文件，并根据需求进行小范围的测试以确保每次修改都不会造成系统故障。

如报错 scm 初始化失败

# 以下在初始化命令的时候做
rm -rf /etc/cloudera-scm-server/db.mgmt.properties

如报错找不到 mysql 驱动

mysql 连接驱动默认文件夹在/usr/share/java;
mysql-connector-java.jar 如果有版本信息，版本信息必须删除，重命名文件;
否则，创建metadata会出现以下错误

UI界面无反应

在安装前的上一步选择同时安装的个数为3;
浏览器有广告拦截插件，需关闭，或者更换浏览器；

未找到任何 parcel

报错详情：

未在已配置的存储库中找到任何 parcel。尝试在更多选项下添加一个自定义存储库。
否则，您可能只能继续使用包。

解决

读不到cdh文件，因为cdh本地存放目录：默认/opt/cloudera/parcel-repo
确认CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha hash值是否正确；
1. 开启manifest.json文件，匹配CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel的hash值；
2. 与CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha hash值对照是否一样，
3. 如果不一样，清空CDH-6.0.1-1.cdh6.0.1.p0.590678-el7.parcel.sha256 文件，按manifest.json写入hash；

选择存储库时卡住了

原因

安装第一次中断了，然后第二次重新进入安装，到这一步的时候点继续没有反应，

解决

去ClouderaManager网页里面把原本添加的几个主机移除，再执行安装操作，就可以点继续了

NameNode 格式化失败

报错详情：

对当前 NameNode 的名称目录进行格式化。如果名称目录不为空，此操作将失败。
命令 (Format (29)) 已失败 Failed to format NameNode.

解决

将namenode的数据目录移出文件夹，然后重试就可以了；
修复后再删除；

Hive 启动报错

报错详情

RROR org.apache.hadoop.hive.metastore.HiveMetaStore: [main]: Metastore Thrift Server threw an exception...
javax.jdo.JDODataStoreException: Required table missing : "`DBS`" in Catalog "" Schema "". DataNucleus requires this table to perform its persistence operations. Either your MetaData is incorrect, or you need to enable "datanucleus.schema.autoCreateTables"

解决：修改配置

hive.metastore.schema.verification
fasle

datanucleus.metadata.validate
hive.metastore.schema.verification
false

datanucleus.schema.autoCreateAll
true

查看权限

use mysql;
select host,user from user;

hive元数据库是否初始化

hive的元数据库是否有其他表
没有初始化，可以通过命令初始化元数据
先删除hive数据库，再重新建立hive数据库，再赋权限，再初始化一次就好了
在 hive bin 目录下执行

./schematool -initSchema -dbType mysql--verbose
./schematool -dbType mysql -

无法找到主机的NTP 服务

报错详情

CDH集群无法找到主机的NTP 服务,或该服务未响应时钟偏差请求

解决

一般情况下,出现无法找到主机的 NTP 服务,或该服务未响应时钟偏差请求；
错误是因为NTP服务异常,
1. 运行 systemctl status ntpd 查看NTP进程，
2. 执行 systemctl restart ntpd 可重启该进程。
ntpq -p 状态详解

st : 越小证明时间越精确；
when : 上一次同步时间是多久之前；
poll : 同步周期是多长；
reach : 同步了多少次了；
delay : 网络造成的延迟；
offset : 于server的时间差异；
jitter : Linux系统于BIOS的时间差

Hue 无法连接hive

报错

hue could not connect to localhost:10000

解决

hive --service hiveserver2 &

netstat -anop | grep 10000
