This should be dropped...

but I can do that on commit, +1 ... I'd like to commit on monday, if there are no objections.

>                 URL: https://issues.apache.org/jira/browse/HBASE-7817
>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 0.94.4
>            Reporter: Ian Varley
>            Priority: Minor
>             Fix For: 0.95.0, 0.98.0, 0.94.7
>         Attachments: HBASE-7817.patch
> In the default hbase-env.sh in trunk, there's a section for lines you can uncomment to
enable JDWP remote debugging:
> {code:none}
>     # Enable remote JDWP debugging of major HBase processes. Meant for Core Developers

>     # export HBASE_MASTER_OPTS=" -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8070"
>     # export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8071"
>     # export HBASE_THRIFT_OPTS="$HBASE_THRIFT_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8072"
>     # export HBASE_ZOOKEEPER_OPTS="$HBASE_ZOOKEEPER_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8073"
> {code}
> However, this is wrong (at least, if you're starting from local source), because somewhere
in the chain of start-hbase.sh, it sources hbase-env.sh more than once, which has the effect
of including these options twice, which makes the JVM barf on startup, saying
> "ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate
jdwp options. Error occurred during initialization of VM; agent library failed to init: jdwp".
> Removing the first re-included instance of $HBASE_MASTER_OPTS (etc.) solves the problem.
This should either be changed in the default or these scripts shouldn't source hbase-env.sh
multiple times I think.
