+Core file is a disk file that records the image of a process' memory in
case the process crashes or terminates abruptly. This image can be later used
to debug the state of process at the time when it was terminated. This
information can be very useful to debug the cause failure.

A core file is a disk file that records the image of a process' memory in
case the process crashes or terminates abruptly. The information in this image
is useful for debugging the state of a process at the time when it was
terminated.
> Packing a core file in hawq
> ---------------------------
>
> Key: HAWQ-1480
> URL: https://issues.apache.org/jira/browse/HAWQ-1480
> Project: Apache HAWQ
> Issue Type: Improvement
> Components: Command Line Tools
> Reporter: Shubham Sharma
> Assignee: Radar Lei
> Fix For: 2.3.0.0-incubating
>
>
> Currently there is no way to packing a core file with its context –
> executable, application and system shared libraries in hawq. This information
> can be later unpacked on another system and helps in debugging. It is a
> useful feature to quickly gather all the data needed from a crash/core
> generated on the system to analyze it later.
> Another open source project, greenplum, uses a script
> [https://github.com/greenplum-db/gpdb/blob/master/gpMgmt/sbin/packcore] to
> collect this information. Tested this script against Hawq's installation and
> it collects the required information needed for debug.
> Can this be merged into Hawq, if yes, I can submit a pull request and test it.
