Phoenix tracing did not start

Explorer

Hi,

I am using hdp 2.4.3.0-227. I am trying to enable phoenix tracing to monitor the queries and to analyze performance. I followed steps outlined here - https://phoenix.apache.org/tracing.html

i placed the hadoop-metrics2-hbase.properties in /etc/hbase/conf

hadoop-metrics2-phoenix.properties in /usr/hdp/2.4.3.0-227/phoenix/bin in all regions servers

Aslo added following properties to hbase.site

<name>phoenix.trace.statsTableName</name> <value>SYSTEM.TRACING_STATS</value>

<name>phoenix.trace.frequency</name> <value>always</value>. After this

I am not clear where to place the ddl for SYSTEM.TRACING_STATS. Also i could not see ./bin/traceserver.py to start

Please advice.

Thanks

I think tracing is not yet part of HDP 2.4. but you can work with HortonWorks support to have a hot fix jar created for you.

@Ankit Singhal: i was trying to explore, phoenix tracing if there is a way to track the long running queries(scans) currently and try to kill them...

I checked https://issues.apache.org/jira/browse/PHOENIX-2640 which is still open.

Also can this tracing be kept on in production always if there is no impact to running queries or to be enabled only during an issue.

Thanks..
