hbase regionserver总出现自动down的情况排查

来源：互联网发布：老子化胡知乎编辑：程序博客网时间：2024/06/09 14:21

最近在调试hbase，10台节点，服务正常后，写入数据，总是出现regionserver自动down的情况，查看日志如下：

分析：

看着像是跟Zookeeper有关系，又了看监控，发现内存有时候降为0，网络的流量比较大，应该是在写入数据，这个问题网上需要调整jvm参数

从ambari上修改：

修改前：
export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -Xmn{{regionserver_xmn_size}} -XX:CMSInitiatingOccupancyFraction=70 -Xms{{regionserver_heapsize}} -Xmx{{regionserver_heapsize}} $JDK_DEPENDED_OPTS"
修改后：
export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -XX:MaxTenuringThreshold=3 -XX:SurvivorRatio=8 -XX:+UseG1GC -XX:MaxGCPauseMillis=50 -XX:InitiatingHeapOccupancyPercent=75 -XX:NewRatio=39 -Xms{{regionserver_heapsize}} -Xmx{{regionserver_heapsize}} $JDK_DEPENDED_OPTS"

修改前：
export HBASE_OPTS="$HBASE_OPTS -XX:+UseConcMarkSweepGC -XX:ErrorFile={{log_dir}}/hs_err_pid%p.log -Djava.io.tmpdir={{java_io_tmpdir}}"
修改后：
export HBASE_OPTS="$HBASE_OPTS -XX:ErrorFile={{log_dir}}/hs_err_pid%p.log -Djava.io.tmpdir={{java_io_tmpdir}}"

解释：堆大小调整为40G，新生代1G，回收算法使用G1。
-XX:NewRatio=39
是新生代和其他的老年代、持久代的比例

1/(39+1) * 40 G
默认的CMS算法总出现异常导致regionserver自杀

-Xmn{{regionserver_xmn_size}} 是配置新生代的
有可能在G1中不适用了，删除掉
