具有JMX导出器的HBase BindException

标签: hbase jmx ambari hdp

我已经在Ambari HDP上部署了HBase。我尝试使用JMX导出器获取HBase指标,因此我在“ hbase-env”中添加了下一个配置:

export HBASE_OPTS="$HBASE_OPTS -javaagent:/opt/jmx_exporter/jmx_exporter_javaagent.jar=7174:/opt/jmx_exporter/hbase/hbase.yml"

我运行HBase没问题,但是当我尝试访问hbase shell时,它将引发下一个错误:

我已经尝试更改JMX导出器的端口,但是始终抛出BindException。如果我在Hbase-env中删除JMX导出器的行,则它可以正常工作,并且可以访问hbase shell。

2 个答案:

答案 0 :(得分:0)

基于下一篇文章:https://blog.godatadriven.com/hbase-prometheus-monitoring,我将以下内容添加到/ usr / bin / hbase中,因此,如果该端口可用,它将仅在第一次导出指标。

if [ `lsof -n -i:7000 | grep LISTEN | wc -l` == "0" ]; then
  export HBASE_OPTS="$HBASE_OPTS -javaagent:/opt/jmx_exporter/jmx_exporter_javaagent.jar=7000:/opt/jmx_exporter/hbase/hbase.yml"
fi

问题是,每次您尝试启动HBase服务时,都会发生端口冲突,因此失败。

答案 1 :(得分:0)

我也一样。即使我将以下代码放在 /bin/hbase 中,我仍然收到此错误:

[root@xxx ~]# hbase shell 检查端口 7000 - 未使用端口 7000 - 使用端口 7000 用法:-javaagent:/path/to/JavaAgent.jar=[host:]:收集器已经注册,提供名称:jmx_exporter_build_info

用于 {7000..8010} 中的端口;做

    if [ `lsof -n -i:$port | grep LISTEN | wc -l` == "1" ]; then
            echo "Checking port $port - port $port in use"
    else
            echo "Checking port $port - port $port not in use - using port $port"
            export HBASE_OPTS="$HBASE_OPTS -javaagent:/hdptmp/jmx_prometheus_javaagent-0.16.0.jar=$port:/hdptmp/hbase_jmx_config.yaml"
            break
    fi

完成
