[IMPALA-2619] create scripts for reliable core file debugging

• Type: Task
• Status: Open

• Affects Version/s: Impala 2.3.0
• Component/s: Infrastructure
• Target Version: Impala 2.7.0

Description

These step by step instructions should be scripted.

On the system where impalad crashed:

gdb -c core /path/to/impalad
(gdb) info shared

# Take this list of .so's and tar them up, being sure to follow symlinks:
tar chvzf so.tar.gz <list of so files>

# Copy the core file, impalad, impalad.debug, and so.tar.gz files in the jira directory on impala-desktop.

On the system where you'll debug:

tar xvf so.tar.gz
gdb impalad
# That should find and load symbols from impalad.debug automatically.
# Tell gdb to look for the copied so's rather than the system so's
(gdb) set sysroot /path/to/extracted/so/tar
# Once the path is changed, then load the core file
(gdb) core core
# Now the core file should be debuggable on the remote system.
