自动删除旋转的gc.log文件

我们有Hadoop群集版本2.6.4,而Metrics Collector安装在我们的一个Linux服务器上

root@master02 ambari-metrics-collector]#  rpm -qa | grep metrics-collector
ambari-metrics-collector-2.6.1.0-143.x86_64

在下面 /var/log/ambari度量收集器 ,我们的gc.log文件来自 七月 去年,我们希望自动删除旋转的gc.log文件

[root@master02 ambari-metrics-collector]# ls -ltr | grep gc.log | grep -v collector| more

从ambari gui中的高级ams hbase env可以看到以下内容:

{% if java_version < 8 %}
export HBASE_MASTER_OPTS=" -XX:PermSize=64m -XX:MaxPermSize={{hbase_master_maxperm_size}} -Xms{{hbase_heapsize}} -Xmx{{hbase_heapsize}} -Xmn{{hbase_master_xmn_size}} -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseCMSInitiatingOccupancyOnly"
export HBASE_REGIONSERVER_OPTS="-XX:MaxPermSize=128m -Xmn{{regionserver_xmn_size}} -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseCMSInitiatingOccupancyOnly -Xms{{regionserver_heapsize}} -Xmx{{regionserver_heapsize}}"
{% else %}
export HBASE_MASTER_OPTS=" -Xms{{hbase_heapsize}} -Xmx{{hbase_heapsize}} -Xmn{{hbase_master_xmn_size}} -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseCMSInitiatingOccupancyOnly"
export HBASE_REGIONSERVER_OPTS=" -Xmn{{regionserver_xmn_size}} -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseCMSInitiatingOccupancyOnly -Xms{{regionserver_heapsize}} -Xmx{{regionserver_heapsize}}"
{% endif %}

我们尝试在hbase_master_opts或hbase_regionserver_opts中设置
这个 -xx:numberofgclogfiles=10 为了只获取10个gc.log文件,但metrics collector未能启动,似乎是因为语法不正确

参考- http://www.oracle.com/technetwork/java/vmoptions-jsp-140102.html

export HBASE_MASTER_OPTS=" -XX:PermSize=64m -XX:MaxPermSize={{hbase_master_maxperm_size}} -Xms{{hbase_heapsize}} -Xmx{{hbase_heapsize}} -Xmn{{hbase_master_xmn_size}} -XX:CMSInitiatingOccupancyFraction=70 -XX:+UseCMSInitiatingOccupancyOnly -XX:NumberOfGClogFiles=1"

请建议如何自动删除旋转的gc.log文件
