备注:
CDH 版本: 6.3.1
背景
CDH集群运行了2个多月了，根目录磁盘使用率接近80%了，需要清理CDH日志。
一.查看问题
CDH的日志文件一般在如下几个目录，可以通过如下代码进行查看。
代码:
cd /var/log/
du -s ./* | sort -nr
cd /var/lib/cloudera-service-monitor
du -s ./* | sort -nr
cd /var/lib/cloudera-host-monitor
du -s ./* | sort -nr
测试记录:
[root@hp1 ~]# cd /var/log/
[root@hp1 log]# du -s ./* | sort -nr

二.清理空间
首先是 /var/log的清理,因为组件较多，需要进入到各个组件的目录下,将out文件和log文件进行删除
cd /var/log/hadoop-mapreduce
cd /var/log/hadoop-hdfs
cd /var/log/zookeeper
cd /var/log/hive
cd /var/log/cloudera-scm-agent
cd /var/log/audit
cd /var/log/hadoop-yarn
cd /var/log/hue-httpd
rm -rf *.out.*
rm -rf *.log.*
其实是监控数据的删除，两个监控累积占了15G左右的空间。
删除监控服务的日志。
cd /var/lib/cloudera-host-monitor/ts/type/partitions
rm -rf type*
cd /var/lib/cloudera-host-monitor/ts/stream/partitions
rm -rf stream*
cd /var/lib/cloudera-host-monitor/ts/ts_stream_rollup_PT600S/partitions/
rm -rf ts_stream*
cd /var/lib/cloudera-host-monitor/ts/ts_type_rollup_PT600S/partitions/
rm -rf ts_type*
cd /var/lib/cloudera-service-monitor/ts/stream/partitions/
rm -rf stream*
cd /var/lib/cloudera-service-monitor/ts/type/partitions/
rm -rf type*
cd /var/lib/cloudera-service-monitor/ts/ts_stream_rollup_PT600S/partitions/
rm -rf ts_stream*
cd /var/lib/cloudera-service-monitor/ts/ts_type_rollup_PT600S/partitions/
rm -rf ts_type*
三.配置shell脚本自动清理
#!/bin/bash
# 清理日志
cd /var/log/hadoop-mapreduce
rm -rf *.out.*
rm -rf *.log.*
cd /var/log/hadoop-hdfs
rm -rf *.out.*
rm -rf *.log.*
cd /var/log/zookeeper
rm -rf *.out.*
rm -rf *.log.*
cd /var/log/hive
rm -rf *.out.*
rm -rf *.log.*
cd /var/log/cloudera-scm-agent
rm -rf *.out.*
rm -rf *.log.*
cd /var/log/audit
rm -rf *.out.*
rm -rf *.log.*
cd /var/log/hadoop-yarn
rm -rf *.out.*
rm -rf *.log.*
cd /var/log/hue-httpd
rm -rf *.out.*
rm -rf *.log.*
# 清理监控日志
cd /var/lib/cloudera-host-monitor/ts/type/partitions
rm -rf type*
cd /var/lib/cloudera-host-monitor/ts/stream/partitions
rm -rf stream*
cd /var/lib/cloudera-host-monitor/ts/ts_stream_rollup_PT600S/partitions/
rm -rf ts_stream*
cd /var/lib/cloudera-host-monitor/ts/ts_type_rollup_PT600S/partitions/
rm -rf ts_type*
cd /var/lib/cloudera-service-monitor/ts/stream/partitions/
rm -rf stream*
cd /var/lib/cloudera-service-monitor/ts/type/partitions/
rm -rf type*
cd /var/lib/cloudera-service-monitor/ts/ts_stream_rollup_PT600S/partitions/
rm -rf ts_stream*
cd /var/lib/cloudera-service-monitor/ts/ts_type_rollup_PT600S/partitions/
rm -rf ts_type*
