Enis Soztutar commented on HBASE-18579:
---------------------------------------

{code}
echo "/tmp/core.%h.%e.%t" >> /proc/sys/kernel/core_pattern
{code}
Other than this, +1.
> Enable core dump by default for docker

> In recent debugging experience, I found that by default the ulimit value
> prohibits the generation of core dump. This makes debugging difficult.
