### 1、Connection failed: \[Errno 111\] Connection refused to XXX:16030 ###

在ambari上启动某台主机上的regionserver时，启动不了，同时在主机上的/var/log/hbase/ 目录中有日志产生。
    日志hbase-hbase-regionserver-XXX.log 中新增内容：
    2016年 11月 30日 星期三 10:06:22 CST Starting regionserver on XXX
    core file size (blocks, -c) 0
    data seg size (kbytes, -d) unlimited
    scheduling priority (-e) 0
    file size (blocks, -f) unlimited
    pending signals (-i) 1031397
    max locked memory (kbytes, -l) 64
    max memory size (kbytes, -m) unlimited
    open files (-n) 10000
    pipe size (512 bytes, -p) 8
    POSIX message queues (bytes, -q) 819200
    real-time priority (-r) 0
    stack size (kbytes, -s) 10240
    cpu time (seconds, -t) unlimited
    max user processes (-u) 16000
    virtual memory (kbytes, -v) unlimited
    file locks (-x) unlimited
    
    另外还会产生一个日志文件hs_err_pid16030.log

解决办法：

在hs\_err\_pid开头的文件中，有提示的办法，在主机上执行命令ulimit -c unlimited，之后在ambari页面上重新启动regionserver，启动成功，告警消失了。

### 2、ERROR \[pool-9-thread-319\] BaseProvider:240 - Caught exception getting JMX metrics : ###

集群ambari中的指标加载不出来，查看34上/var/log/ambari-server/ambari-server.log有如下错误：
    
    29 Nov 2016 16:18:18,337 ERROR [pool-9-thread-319] BaseProvider:240 - Caught exception getting JMX metrics : 
    Connection refused, skipping same exceptions for next 5 minutes
    java.net.ConnectException: Connection refused

解决办法：  
昨天有问题，当时没有解决，今天集群自己恢复了，可能是时间同步的问题

### 3、There are 1 stale alerts from 1 host(s) ###

集群时间有问题了，同步时间后自动恢复正常

### 4、Connection failed: \[Errno 111\] Connection refused to XXX:50010 ###

2017-04-18 14:23:25,008 WARN datanode.DataNode (DataNode.java:checkStorageLocations(2439)) - Invalid dfs.datanode.data.dir /data1/hadoop/hdfs/data : 
    org.apache.hadoop.util.DiskChecker$DiskErrorException: Directory is not writable: /data1/hadoop/hdfs/data
    。。。
    2017-04-18 14:23:26,751 WARN common.Storage (BlockPoolSliceStorage.java:loadBpStorageDirectories(221)) - Failed to analyze storage directories for block pool BP-1071526479-192.16.10.34-1472798972660
    java.io.IOException: BlockPoolSliceStorage.recoverTransitionRead: attempt to load an used block storage: /data2/hadoop/hdfs/data/current/BP-1071526479-192.16.10.34-1472798972660
    at

Directory is not writable: /data1/hadoop/hdfs/data 。

/dev/sdb1 ext4 3.6T 137G 3.3T 4% /data1

一块磁盘出问题了

解决方法：修改hdfs-sites配置属性  
dfs.datanode.failed.volumes.tolerated值为1；重启动datanode即可。

1、卸载磁盘
    查看使用/data1的进程，并杀掉
    [root@XXX ~]# fuser -m /data1
    /data1:               4036m 26457c
    [root@XXX ~]# kill -9 26457
    [root@XXX ~]# fuser -m /data1
    /data1:               4036m
    [root@XXX ~]# kill -9 4036
    
    2、卸载磁盘
    umount /dev/sdb1 /data1
    
    3、格式化磁盘
    mkfs.ext4 /dev/sdb1

### 5、DataNode Health: \[Live=18, Stale=0, Dead=1\] ###

DataNode Health Summary
    DataNode Health: [Live=18, Stale=0, Dead=1]
    DataNode Health: [Live=18, Stale=0, Dead=1]

解决办法：

Dead掉的是主机能ping通，但是ssh的时候秒退，估计是客户端连接数过多，就会这样，要修改配置文件，把连接数改大

### 6、XXX is not sending heartbeats ###

解决办法：

1、查看agent是否在运行，显示没有
    sudo ambari-agent status
    
    2、启动agent
    sudo ambari-agent start

### 7、ambari中hbase报错 ###

2017-08-03 09:20:59,089 INFO  [regionserver/XXX/192.16.10.25:16020] 
    regionserver.HRegionServer: STOPPED: 
    Unhandled: org.apache.hadoop.hbase.ClockOutOfSyncException: 
    Server XXX,16020,1501723257281 has been rejected; 
    Reported time is too far out of sync with master.  
    Time difference of 224557ms > max allowed of 30000ms

解决办法：

同步集群时间

### 8、sqoop导数据报错：Container killed on request. Exit code is 143 ###

调大如下两个属性值
    mapreduce.map.memory.mb
    mapreduce.reduce.memory.mb

### 9、ambari中重启某台主机的组件卡住 ###

    04 Aug 2017 09:02:07,517 ERROR [qtp-ambari-client-986626] MetricsRequestHelper:121 - Error getting timeline metrics : Read timed out Can not connect to collector, socket error.

    java.net.ConnectException: Connection refused
    	at java.net.PlainSocketImpl.socketConnect(Native Method)
    	at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350)

解决办法：

参考[https://community.hortonworks.com/questions/49766/ambari-unable-to-start-any-service-after-successfu.html][https_community.hortonworks.com_questions_49766_ambari-unable-to-start-any-service-after-successfu.html]

解决方法：
    a）在data主机重启ambari-agent
    ambari-agent restart
    
    b) 在master1主机重启ambari-server
    ambari-server restart

### 10、Connection failed to http:/XXX:50075 (<urlopen error \[Errno 111\] Connection refused>) ###

### 11、通过beeline方式调用hql报错问题 ###

解决办法：  
通过查找资料和测试，发现原因是 ~/.beeline/history 文件过大导致的，把该文件删除后测试成功
