This folder contains example byteman scripts (http://byteman.jboss.org/) to help
|
||
|
|
Hadoop debuging.
|
||
|
|
|
||
|
|
As the startup script of the hadoop-runner docker image supports byteman
|
||
|
|
instrumentation it's enough to set the URL of a script to a specific environment
|
||
|
|
variable to activate it with the docker runs:
|
||
|
|
|
||
|
|
|
||
|
|
```
|
||
|
|
BYTEMAN_SCRIPT_URL=https://raw.githubusercontent.com/apache/hadoop/trunk/dev-support/byteman/hadooprpc.btm
|
||
|
|
```
