Adding a javaagent in CDH 5 or 6.2

HadoopBD — Fri, 16 Sep 2022 14:39:10 GMT

We are trying to pull metrics into Promtheus and

for the life of me I spent most of lastnight trying to get CDH 6.2 to work with a javaagent. I read a previous post where someone was have a heck of a time with jmx exporter and Ambari, so I'm assuming this is also an issue in CDH?

If I goto:

HBase Service Environment Advanced Configuration Snippet (Safety Valve)

and add this:

HBASE_MASTER_OPTS=-Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.port=10110 -javaagent:/run/cloudera-scm-agent/jmx_prometheus_javaagent-0.14.0.jar=9214:/run/cloudera-scm-agent/hbasemaster.yml"
HBASE_REGIONSERVER_OPTS=-Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.local.only=false -Dcom.sun.management.jmxremote.port=10111 -javaagent:/run/cloudera-scm-agent/jmx_prometheus_javaagent-0.14.0.jar=9215:/run/cloudera-scm-agent/regionserver.yml"

and then restart the service

The service WILL not restart and stderr shows:

Error opening zip file or JAR manifest missing : /run/cloudera-scm-agent/jmx_prometheus_javaagent-0.14.0.jar

I've verified all files are there :
-rw-rw-rw- 1 root root 405K Sep 4 12:20 jmx_prometheus_javaagent-0.14.0.jar
-rwxr-xr-x 1 root root 283 Oct 14 02:04 namenode.jml
-rwxr-xr-x 1 root root 283 Oct 14 02:04 datanode.jml
-rwxr-xr-x 1 root root 283 Oct 14 02:04 regionserver.jml
-rwxr-xr-x 1 root root 283 Oct 14 06:17 hbasemaster.jml
-rwxr-xr-x 1 root root 283 Oct 14 06:57 yarn.jml

I've tried to modify the hbase-env.sh directly, but of course there are so many and that I can't seem to get it to work. Has anyone got this working in CDH5 or CDH6 and if so, can point me in the right direction

See following resource, this fixed it for me: https://community.cloudera.com/t5/Support-Questions/Customize-Hbase-JVM-settings-in-CDH-5-4-2/td-p/30997

put everything in "HBase Service Environment Advanced Configuration Snippet (Safety Valve)"

Hello @HadoopBD

We hope the Steps shared by @sebastienleroy via the Community Link has worked for you. Additionally, Sharing 2 Links which document the same for ensuring HBase is monitored with Prometheus.
