Hi @zj5220924, thank you for reporting this bug! Can you share the content of the default config file?

Yes, I already put the mysql defaults config file into my note:

@davidducos
I had segmentation fault when I executed like this:

mydumper -o dump -c -e -h 127.0.0.1 -u $DB_USER -p $DB_PASS $DB_NAME

instead of:

mydumper -o dump -c -e -h 127.0.0.1 -u $DB_USER -p $DB_PASS -B $DB_NAME (missing -B switch).

Probably related?

Oh!!! I found the problem, currently --stream which is being set by default when you use DB_NAME doesn't support compression!!
This should work:

mydumper -o dump  -e -h 127.0.0.1 -u $DB_USER -p $DB_PASS $DB_NAME
