Nick Dimiduk commented on HBASE-27651:
--------------------------------------
My initial reaction was to change our container configuration to launch
processes with {{bin/hbase}} instead, but it seems {{bin/hbase-daemon.sh}} has
additional responsibility pertaining to cleaning up znodes. I this is
not/cannot be done from {{bin/hbase}} because it uses {{exec}} to launch the
jvm process.
An alternative approach would be to implement the node cleanup as a shutdown
handler in the JVM.
> hbase-daemon.sh foreground_start does not propagate SIGHUP or SIGTERM properly

> Priority: Minor

> Running HBase in a container environment, launched using
> {{{}bin/hbase-daemon.sh foreground_start ...{}}}. Signaling the container for
> config refresh or for graceful termination doesn't make it through to the JVM
> process. Rather, the {{trap}} function is unconditionally sending {{{}kill
> -9{}}}.
