[jira] [Created] (HBASE-29853) Move from async profiler binary to a maven dependency
Aman Poonia created HBASE-29853:
-----------------------------------
Summary: Move from async profiler binary to a maven dependency
Key: HBASE-29853
URL: https://issues.apache.org/jira/browse/HBASE-29853
Project: HBase
Issue Type: Improvement
Affects Versions: 3.0.0-beta-1, 4.0.0-alpha-1, 2.6.4, 2.5.13
Reporter: Aman Poonia
Assignee: Aman Poonia
Fix For: 2.7.0, 3.0.0-beta-2, 2.6.5, 2.5.14
* *Velocity 2.4* disallows hyphens in variable names, requiring template changes.
* Updating the syntax now prepares us for upgrading to newer Velocity versions.
* This improves compatibility with plugins like {*}maven-remote-resources-plugin{*}, which use the latest Velocity.
* The current setup is pinned to {*}Velocity 1.7{*}, while the latest version ({*}3.3.0{*}) runs on the *Velocity 2.x engine* by default.

+1. It can definitely be a pain for some admins to get new binaries like
async-profiler installed across their machines outside of Ozone. How would
we invoke the profiler after adding the dependency? I think the usual
jcmd + pid option would still work, but it also looks like HBase added a
Rest endpoint to do remote profiling. We could also consider adding an
`ozone debug profile` CLI wrapper with common options for local or remote
profiling.

Didn't realize async profiler comes in maven dependency form as well. The
jar file itself is 890kb, not too terrible. Could be useful if we ship it
by default.
